The Daily Space - Newly Discovered Bright Transient Radio Source is a Mystery Sep 26, 2023

From Jan 27, 2022.

Scientists using the Murchison Widefield Array in Australia recently discovered an extremely bright source of radio waves, releasing bursts of energy three times an hour. That timing makes the object behave unlike anything else seen to date, leaving the research team with a new mystery to unravel. Plus, everything else is about water today, all over the solar system, and we present this week’s What’s Up segment.

Astronomy Cast Ep. 690: Climate on Mars - From Ice Caps to Dust Storms Sep 25, 2023

https://www.youtube.com/watch?v=xR0fmR710rc

Streamed live on Sep 18, 2023.

We’ve looked at Earth’s changing climate, now let’s see what it’s like for another world: Mars. Much looks familiar, but some of it is totally alien, from ice caps of frozen carbon dioxide to planetary dust storms that can obscure the entire world from view.

Travelers in the Night Eps. 711 & 712: First One & Tiny Travelers Sep 24, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Asteroid hunters were able to discover a small Earth approaching asteroid after 57 nights of continuous rain and clouds.

- Although small space rocks pose no threat to humans, they are an interesting part of our environment, offer a chance for asteroid hunters to develop their tracking skills, and occasionally provide an opportunity for a meteorite hunter to touch an object from outer space.

The Cosmic Savannah Ep. 49: SALT - Spectroscopy Sep 23, 2023

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

The IAU celebrates Women and Girls in Astronomy Month throughout February, from February 11th, 2022 in tandem with the United Nations’ International Day of Women and Girls in Science, to International Women’s Day on 8 March.

To celebrate this we speak with Dr. Elizabeth Naluminsa, a wonderful woman who is one of the first Ugandan women to obtain her PhD in Astronomy. Her dissertation topic was “Star Formation and Disk Stability in Nearby Galaxies”, which puts her at the forefront of galaxy evolution studies.

Liz is now working at the South African Astronomical Observatory with the Southern African Large Telescope ( SALT ) and she speaks with us about her work on SALT and SALT instrumentation.

EVSN - Will Asteroid 2023 DW Collide with Earth in 2046? (All signs point to no.) Sep 22, 2023

From July 5, 2023.

A new asteroid has been discovered with an orbit that crosses our own planet’s orbit. In general, this object and Earth are very good and not trying to occupy the same space at the same time, and we’ve managed to coexist for a fair amount of time. We are going to have a close approach, however, in 2046, and for the first time in a long time, the potentially dangerous asteroids list actually gave us something to worry about. (This episode originally aired on television March 18, 2023.)

Awesome Astronomy - The Antikythera Mechanism Sep 21, 2023

https://www.youtube.com/watch?v=aDU3XX49quI

Ralph Wilkins hosts.

Damien Phillips, John Wildridge and Dustin Ruoff produce.

From Feb 25, 2022.

This is the machine made over a thousand years ahead of its time!

Made in ancient Greece more than 2,000 years ago and lost in the Aegean Sea. It was so sophisticated that nothing like it would be invented or made for another 1,500 years.

Found in a shipwreck by sponge divers, the Antikythera Mechanism has been compared to a computer and often seen as the most advanced technology the world had seen. Not just for it’s time but more advanced than anything we’d see until the 1400s.

Thanks to Jonathon Zellar for suggesting this incredible subject!

Travelers in the Night Eps. 709 & 710: Catching Asteroids & Boomer Sep 17, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Asteroid mining Is possible. It might be possible to catch an asteroid, place it into Earth orbit, and thus provide a ready source of precious metals and water for space colonists to use.

- The fireball meteor streaking across the sky the early evening of January 17, 2018, witnessed by 700 observers in 11 States and Canada was also recorded by infrasonic microphones and seismometers. Scientific studies of this event gives researchers the ability to assess the risks presented by the 2,000 large fireball meteor explosions which occur each year world wide and will allow scientists to detect any secret nuclear tests being conducted by rogue individuals or governments.

EVSN - Is 2023 The Year Of Io? Sep 15, 2023

From Jun 22, 2023.

In general, the kind of year we’ll experience gets its label at the end of the year. 2005 was the year of the never-ending hurricane season. 2017 was the year we experienced an eclipse and lost Cassini. 2020 was the year satellite constellations went from a handful to hundreds of spacecraft. 2022 was the year of Mars exploration with Curiosity, Percy, Ginny, Insight, and Tianwen-1.

Each year gets to define itself, and it is up to us to fight or embrace what that year brings us. This year, 2023, is still young, but I’m going to guess that come January 2024, this will be the year of Io. (This episode originally aired on television March 11, 2023)

Astronomy Cast Questions Show: Matter Balance, Jumping Light Speed and Black Hole Star Formation Sep 11, 2023

From June 25, 2009.

Why was there a difference between the amount of matter and antimatter at the beginning of the Universe? Mathematics lets us travel faster than light speed, so why can’t we? And are there stars forming around black holes?

- Why was there a difference between the amount of matter and antimatter at the beginning of the Universe? Do black holes have something to do with this?

- Mathematically, we can have a velocity greater than the speed of lights lets us travel faster than light speed, so why can’t we?

- Can stars form in accretion disks around black holes?

- How much precision is needed to keep space telescopes focused on one spot? I have a hard enough time keeping my camera steady!

- How can matter exist with antimatter?

- What causes sunspots and do they influence Earth in any way?

- How do we know what the speed of light is? How can we measure something that fast and how did scientists figure that out?

- Would life as we know it be able to survive around a Red Dwarf?

- Could matter escape from the event horizon of two black holes colliding?

- Why is it so bright in the center of the galaxy with a black hole there?

- What is behind a black hole?

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Even though humans have been aware of the planet Saturn from from the dawn of history this beautiful object still offers mysteries for us to explore.

- In 2018, July and August were cloudy and rainy in both Arizona and Hawaii sidelining the worlds two most productive asteroid hunting surveys. A cost effective way to make the Earth's planetary defense system more weather proof is to put a network of asteroid hunting telescopes around the world to discover and track potentially dangerous nearby neighbors.

NOIRLab - The First Magnetar Progenitor Sep 09, 2023

Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery.

New observations by a team of astronomers, including NSF’s NOIRLab’s Dr. André-Nicolas Chené, may shed important light on the origin of these magnetic powerhouses. Using various telescopes around the globe, including the Canada-France-Hawai‘i Telescope (CFHT) on Maunakea, the researchers have identified a new type of astronomical object — a massive magnetic helium star (an unusual variant of a Wolf-Rayet star), which may be the precursor of a magnetar.

In this podcast, André-Nicolas Chené describes the process of finding the first known potential magnetar progenitor.

Bios:

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Dr. André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini’s user support effort. André-Nicolas’s research interests are massive stars, hot winds, star clusters, and stellar evolution.

The Daily Space - Origin of Earth’s Water: A New Hypothesis Has Entered the Chat Sep 06, 2023

From January 26, 2022.

For decades, scientists have been trying to work out just how the Earth got all its water, and the prevailing theory was that comets and asteroids brought it, and we have evidence for that mechanic; however, a new hypothesis has provided evidence that the water was already here, locked away in hydrous minerals in a very iron-poor core. Plus, magnetic fields, subatomic particles, life on the ocean floor, a geology mystery solved, and this week in rocket history covers a space shuttle mission with some really neat science.

Astronomy Cast - Questions: An Unlocked Moon, Energy Into Black Holes, & the Space Station's Orbit Sep 04, 2023

http://www.astronomycast.com/archive/

From May 21, 2009.

- What would happen if the Moon was rotating fast enough that it was not tidally locked to the Earth?

- When light and matter go into a black hole, where do they go?

- Why does the space station’s orbit seem to oscillate between 60 degrees north latitude and 60 degrees south?

- What do telescopes pick up when they look at different objects — is it light waves or individual photons?

- Is Dark Matter “out there” or it is all around us?

- Did time pass so slowly during the Big Bang that it occurred infinitely long ago?

- If the sun classified as yellow, why is the color of daylight white?

- Since the beginning of the show, has any of the science discussed changed?

- Could Hubble or Cassini be boosted out in to space to save the spacecraft from destruction?

Travelers in the Night Eps. 705 & 706: One Half Inch & Wonders to Behold Sep 03, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Fuzzy, spread out, asteroid images due to atmospheric and or equipment produced distortions can cause important objects to slip through an asteroid hunter's discovery images undetected. A careful monitoring of the temperature at a number of different locations in the observatory environment and using fans and other techniques to minimize temperature differences restores the power of a telescope so that it can detect possible asteroid threats to planet Earth.

- From the time 3 million years ago that our ancestor Lucy walked in what is now Ethiopia until the widespread use of electric lighting began in the 1880s the changing panorama and awe inspiring beauty of the natural night sky was available to most human beings.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Exciting new research indicates that there could be a lake of liquid water beneath the south Martian polar cap. Further research will be required to determine if this briny pool could be the home of martian creatures.

- There are likely to be hundreds smaller than softball sized and perhaps several dozen football to beachball sized, natural Earth mini moons, which are so small and fast moving that they are able to slip through asteroid hunters images without being detected.

EVSN - Cosmology: From Particles to Galaxy Clusters Aug 25, 2023

From May 24, 2023.

We live at a time when technological advances are allowing us to explore ideas faster than ever before. So today, we bring you lab results on ice that affect how we see the outer solar system, and observations of galaxies that affect our understanding of the universe’s formation. We go from things smaller than a proton – which we just learned is 0.73 femtometers across -- to galaxy clusters 10s of millions of lightyears across. It’s all tied together, and we’ll tell you how.

UNAWE Space Scoop - A Rare Cosmic Magic Jug Aug 24, 2023

https://spacescoop.org/en/scoops/2318/a-rare-cosmic-magic-jug/

I present to you the “Cosmic Jug"!

Astronomers recently captured this rare structure using NSF NOIRLab’s Gemini South telescope. The image is that of a reflection nebula, nicknamed the Toby Jug Nebula, resembling the shape of an old style English pottery jug.

A Toby Jug? Whaaaaat? No, really. Go to Wikipedia and type it in. It’s fascinating!

Cheap Astronomy - Dear CA #97: Only So Much Aug 22, 2023

You can’t have everything.

– How big is the Universe?

Needless to say we just don’t know, beyond saying it’s at least as big as the observable Universe and very likely bigger. The real answer to the question may just be unknowable, since we will never see beyond the observable universe.

– Are we really not going to Mars in the 2030s?

Well, probably not. NASA’s moving target is now 2037, it was previously running with 2033 until an independent review looked at their current plan and said no way and also said no way to the next launch window in 2035, so it’s 2037 now – which Cheap Astronomy guesses will be pushed into 2040 in about three years.

Astronomy Cast Questions Show: The Source of Atmospheres, the Vanishing Moon, and a Glow After Sunset Aug 21, 2023

From May 7, 2009.

How do planets get their atmospheres? What would happen to the Earth if the Moon just disappeared? And what’s that strange glow we see after sunset?

- What would happen if the Moon disappeared — would that change Earth’s orbit?

- How do planets get atmospheres?

- I see a faint glow after sunset in the East — what could it be?

- Can light get stuck in orbit around a black hole?

- Where on Earth would I weigh the most?

- How much less would I weigh if the moon was directly overhead?

- How is ionized hydrogen detected in space?

- Do we live in an unbalanced Universe?

- Why do some celestial objects form in disks and others don’t?

- Could a spacecraft perform a “solar system assist,” in the way we do gravity assists?

- If Earth had no axial tilt, how eccentric would its orbit have to be to have seasons like we have now?

- Does light have mass?

- The Cosmic Microwave Background is a redshift of the Big Bang. If one could travel near light speed, would that counteract the redshift?

- Is repulsive gravity real?

Travelers in the Night Eps. 701 & 702: Touching the Sun & 20 Years Aug 20, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Imagine a spacecraft traveling at a speed that would take it from New York to Tokyo in less than a minute, a mere 4 million miles from the surface of our Sun, where it would be exposed to about 500 times the solar radiation we receive here on Earth. Not science fiction but science fact for the NASA Parker Solar Probe on one of its final laps around our star.

- It has been 20 years since the world woke up to the news that a half mile diameter asteroid, 1997 XF11, discovered by Space Watch on Kitt Peak, had a slight chance of impacting the Earth in 2028. The NASA and JPL's Center for Near Earth Object Studies or CNEOS (see-neos) for short maps space rocks orbits, predicts when they will come close to us, and reliably determines each one's chance of impacting Earth.

NOIRLab - Backyard Worlds: Cool Neighbors Aug 12, 2023

Brown dwarfs are small and dim stars that glow feebly in the infrared and are very difficult to detect. A recently launched citizen science project, Backyard Worlds Cool Neighbors, enlists the public to help identify brown dwarfs from data taken by the NASA Wide Field Infrared Explorer (WISE) satellite. In this podcast, Aaron Meisner talks about this new project and how the public can help find these elusive brown dwarfs.

Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Aaron Meisner is an astronomer at NSF’s NOIRLab in Tucson affiliated with Kitt Peak National Observatory. Aaron works on Kitt Peak’s Dark Energy Spectroscopic Instrument (DESI) project, a newly installed spectrograph at the Mayall 4-meter telescope. He specializes in building astronomical maps using large data sets at visible and infrared wavelengths. These maps are used to search for moving celestial objects, like new neighbors to the Sun and hypothesized planets in the far reaches of our own solar system. To this end, Aaron co-founded the popular Backyard Worlds: Planet 9 citizen science project and the Backyard Worlds: Cool Neighbors project.

Austin Humphreys is a Banneker Key scholar and a rising senior at the University of Maryland, College Park working towards a dual degree in astronomy and physics. Working remotely from Maryland with the Backyard Worlds: Cool Neighbors team, he is an experienced coder having experience in both physics-based and astronomy-based research projects as a part of his undergraduate education, ranging from plasma physics simulations to photometric analysis of planetary nebulae. Prior to his college education, he had the opportunity to be an observational assistant at the Maryland Science Center's Crosby Ramsey Memorial Observatory for three years where he would operate and maintain an 8-inch refractor telescope for the public.

EVSN - Space Science Potpourri & A More Hopeful Look at Climate Change Aug 11, 2023

From May 12, 2023.

This episode has a little bit of everything as we bring you results from astronomers, geoscientists, climate scientists, imaging scientists, glaciologists, meteorologists, planetary scientists, engineers, and even bioarchaeologists. This diversity of research allows us to better understand our world and beyond.

In our first segment, we look at how our ecosystem and past cultures rebounded after prior naturally occurring climate events. It's unclear if this research will help us better recover from the climate change we're currently facing, but maybe it will give us hope.

From our world, we travel outward, looking at the meteorology of Mars, future technology for space exploration, and the star catalogs that will help us define our place in space. (This episode originally aired on television January 28, 2023)

Awesome Astronomy - “How to Grow a Supermassive Black Hole” with Dr. Becky Smethurst Aug 09, 2023

Dr. Jenifer “Dr. Dust” Millard solo hosts!

Damien Phillips, John Wildridge and Dustin Ruoff produce.

Once a year, astronomers descend upon an unsuspecting UK city in the greatest gathering of astronomically curious minds: the National Astronomy Meeting, otherwise known as NAM (no, not that ‘Nam, though it is quite the battle of the minds). Jen was lucky enough to attend this year and this episode is the first in a series of talks recorded at NAM 2023.

We’re delighted to bring you the expertise of none other than Dr. Becky Smethurst of Oxford University (you may know her as Dr Becky on Youtube). In this talk, Dr. Becky teaches us how to grow a supermassive black hole – and it’s not as easy as you think! Always picture a black hole as a gigantic hoover, sucking up everything that dares to stray too close? Think again…

Cheap Astronomy - Dear CA # 096: Touring the Solar System Aug 08, 2023

Next steps…

- What’s all the fuss about Venus?

In June 2021, NASA announced two new Venus missions, Veritas (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) which is expected to happen in 2028 and DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging, Plus) which is expected in 2029 or 2030.

- Can our Mars-bound astronauts survive years of exposure to space radiation?

Well yes, they can potentially, but solutions are yet to be agreed upon, let alone implemented. A radiation shielding solution for a Mars-bound spacecraft, is either going to add a lot of mass if it’s physical shield or draw a lot of power and still add some mass if it’s a magnetic shield. You also need solutions for extra vehicular activities, that is space suit shielding.

Travelers in the Night Eps. 697 & 698: Double Trouble & Aliens? Aug 06, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

From June 17 & 24, 2022.

Today's 2 topics:

- Asteroid hunters have discovered a strange asteroid pair. How they came to be together and what humans would do if such a large double trouble object is heading for us remains a mystery.

- Most Astronomers find it hard to believe that given perhaps a trillion planets in the Milky Way alone that our Earth is the only one which hosts living organisms. It is both exciting and terrifying to realize we have no concept of what living forms may exist outside Earth in the Milky Way.

Escape Velocity Space News - New Science From AAS Rearranges Our Understanding of the Universe Aug 04, 2023

From May 9, 2023.

Hello and welcome! This show - Escape Velocity Space News - is new, and we’re so glad that you’re here with us, right from the beginning. Dr. Pamela Gay, along with a great production team, is here to put science in your brain. In this episode, we’re going to bring you the best of what’s been discovered and dive deep into the hottest topic of the week - the infrared universe. From stunning images from the JWST to better-resolved star formation seen by ESO’s VLT, this redder-than-red color of light has been all the rage in this season’s best science papers.

Also joining us is aerospace journalist Erik Madaus, who brings us a rundown of last year's best launches and the stats for what was a truly bizarre launch year for the European Space Agency and an amazing year for SpaceX. We bring you all of this and more, right here on Escape Velocity Space News. (This episode was originally recorded for television on January 21, 2023)

8th - Last quarter Moon

Jupiter 3-degrees below Moon in early morning sky

10th - Mercury at greatest Elongation 27-degrees in Evening Sky - tough in very bright dusky sky

10 Hygiea at opposition m=9.6
Hygiea is a major asteroid and possible dwarf planet located in the main asteroid belt. With a diameter of 434 kilometres and a mass estimated to be 3% of the total mass of the belt, it is the fourth-largest asteroid in the Solar System by both volume and mass.
Annibale de Gasparis discovered Hygiea on 12 April 1849.
Named after the Greek Goddess of Health.
On Aquarius Capricornus Border.

What is an Occultation?

From here the Moon Passes in front of Antares in the Daylight sky just a few minutes before Sunset, around 8pm, however, the Moon is readily visible in the daytime around 1st quarter and with the Moon as a guide you might find Antares. We can easily see the reveal at about 9pm when it’s dark.

26th - Asteroid 8 Flora at opposition m= 8.3

Discovered by J. R. Hind on 18 October 1847.
The name Flora was proposed by John Herschel, from Flora, the Latin goddess of flowers and gardens.

Travelers in the Night Eps. 695 & 696: A Large Visitor & Botswana Fragment Jul 30, 2023

From June 3 & 10, 2022.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Statistically, asteroid hunters are thought to have discovered 90% of our potentially dangerous celestial neighbors greater than 1 KM in diameter. Thus my Catalina Sky Survey teammate Greg Leonard was surprised to discover 2018 MD1, an unknown very large asteroid moving through the constellation of Perseus.

- An object is tracked in outer space, seen to explode in our atmosphere, and had a fragment of it discovered on the ground. Its analysis will help humans to prepare for and defend against a much larger object with our number on it.

UNAWE Space Scoop - When Exactly Do We Celebrate Planet Birthdays? Jul 29, 2023

https://spacescoop.org/en/scoops/2317/when-exactly-do-we-celebrate-planet-birthdays/

Just how young can a proto-planetary disk be and be forming planets? Proto-planetary discs only exist for a few million years, which means that all planet formation in the system must take place within this, uh, narrow time frame.

But until now, astronomers have not been able to pinpoint how fast planets form in these discs. After years of study and observation of proto-planetary discs, astronomers found these discs have even deeper mysterious layers of structure within them.

Cheap Astronomy - Dear CA Ep. 95: Our Noisy Universe Jul 25, 2023

Noise without sound!

– What’s the latest on magnetars?

Magnetars are a type of neutron star, that has a very powerful magnetic field. That magnetic field slowly decays as the magnetar releases flashes of gamma or xrays so magnetars only last briefly as magnetars, for around 10,000 years, before they drop back to being plain, old neutron stars. Indeed, there is now a suggestion now that many, if not all neutron stars may spend a small part of their lives as magnetars.

– Is there a cosmic gravitational wave background?

Well yes there is, although all we are really saying here is that the Universe contains a lot of background noise in the form of gravitational waves because the Universe is full of moving massive bodies that interact with each other. The real interest here is whether there is some kind of background hum associated with the Big Bang, which might then confirm (or otherwise) our speculations on the events in the very first second of the Universe, including our speculation about there having been early rapid inflation, which would have been a very dramatic and dynamic process and may have left the Universe still resonating with its impact.

Astronomy Cast - Student Questions: Curtis High School Jul 24, 2023

From Feb 15, 2008.

This is our second installment in our series of student questions shows and these questions come to us from Curtis High School. Thanks to GLAST, Astronomy Cast is now able to provide equipment to send to high school teachers who want to Pamela and Fraser to do a special questions show just for their class. We will be making this shows available on the feed on days other than Monday (that’s still reserved for your regularly scheduled Astronomy Cast).

Outer Space: Hi, I’m Outer Space. My question is, besides dark matter and dark energy, is there any possibility there’s anything else in outer space?

Anonymous: Hello, this is Anonymous. I would like to know, since I heard about the new program for bringing life to Mars, I wonder if the big storm forming around Mars will have any conflict with the human development on Mars.

Rocks: Rocks here, what are the possibilities that white holes are really out there?

Santa’s Little Helper: Hi, this is Santa’s Little Helper, I was wondering if we’re at all close to finding intelligent life in outer space.

Star: Hi, this is Star. My question is, if a planet were located near a black hole, what would happen to it?

Sleepy: Hi this is Sleepy. Theoretically, if you have a white hole and a black hole next to each other, what would happen?

Leather Jacket: Hi, this is Leather Jacket. What are the goals of the International Space Station?

Major Tom: This is Major Tom from Ground Control. I’m asking about the manned exploration to Mars. I want to know what you think about it, and I also want to know if you think we will benefit from it and how.

Doctor Love: Hello, this is Doctor Love. I want to know the difference between a red supergiant and a blue supergiant.

Small Stick: Hi, my name is Small Stick. I want to know what will happen to the Earth when the Sun becomes a red supergiant.

Travelers in the Night Eps. 693 & 694: Comet Leonard III & Comet Catalina Jul 23, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- My Catalina Sky Survey teammate Greg Leonard knew he had bagged his third comet when he spotted an unknown fuzzy object with a broad tail moving through the constellation of Pisces. Eventually when P/2018 L5 (Leonard) looses its volatile materials Comet Leonard will become one of the countless millions of main belt asteroids circling our Sun.

- Comet C/2018 M1 (Catalina) is eternal in the sense that it will likely wander the vast space between the stars in our Milky Way Galaxy until the end of time.

Guide To Space - How Many Stars In The Universe? Jul 21, 2023

ttps://www.youtube.com/watch?v=iujHbTvljdQ

From Jun 3, 2013.

In this short explainer video, Universe Today publisher Fraser Cain explains just how many stars there are. How many can you see with your eyes, with binoculars or a small telescope? How many stars in the Milky Way? How many in the entire Universe?

Short answer... a lot.

Astronomy Cast - Student Questions: Farmersburg School Jul 17, 2023

http://www.astronomycast.com/2008/01/student-questions-farmersburg/

From January 6, 2008.

Thanks to GLAST, Astronomy Cast is now able to provide equipment to send to high school teachers who want to Pamela and Fraser to do a special questions show just for their class. We will be making this shows available on the feed on days other than Monday (that’s still reserved for your regularly scheduled Astronomy Cast). This is the first one available and comes with questions from Farmersburg High School.

Sierra: We learned in class that stars emit radio waves. My question is, what do radio waves given off by stars sound like?

Alex: We learned that black holes absorb everything. My question is, what happens to the energy that goes into a black hole?

Lacy: If the ozone layer protects us from the Sun, why can’t we look at the Sun?

Jake: Are all wavelengths of the electromagnetic spectrum absorbed by a black hole?

Alexis: Since the Sun gives off harmful rays, could it help if we figured out how to block all the rays that are harmful and trigger cancer?

Carol-Beth: How hot is the hottest star, and how do we know?

Haley: Why can’t we see the rays like microwaves, infrared or radio waves, but we can see other light rays?

Jake: Are there any known waves that travel faster than light, and if so, how do we detect them?

Cody: How do you tell the difference between a black hole and nothing in space?

Once again, we’ve reached the end of a season here on Astronomy Cast, and it’s time for the summer hiatus.

See you in September!

UNAWE Space Scoop - Stranger Things in a Stranger World Jul 15, 2023

Hosted by Avivah Yamani.

On a clear night sky, head out to the backyard with star charts or night sky apps and look up. Can you spot the constellation Pisces? Did you know there is a strange world in the direction of this constellation? Astronomers recently found evidence of stranger things happening on this planet! WASP-76b is an exoplanet almost the size of Jupiter, located 634 light years away from our Earth. The planet orbits super close to its host star – almost 12 times closer than mercury is to the Sun! So close that the star heats its atmospheres to scorching 2000°C.

Deep Astronomy - Mystery of Ultra Diffuse Galaxy with NO Dark Matter Solved Jul 14, 2023

https://www.youtube.com/watch?v=yXQwr7BhzOM

From Jun 7, 2019.

In this episode, remember that ultra diffuse galaxy I told you about in SFNs 226 and 232? You know, the one with NO dark matter? Well turns out there is dark matter there after all.

This was always a controversial finding, back in SFN 226 I reported that the group who found Dragonfly 44, an ultra diffuse galaxy with very little dark matter in it, had also taken a closer look at another galaxy, NGC1052-DF2 and wrote a paper, in Nature of all places, announcing that according to their observations, this galaxy rotated just like a galaxy would if it had no dark matter at all in it.

NOIRLab - A New way To Annihilate A Star Jul 08, 2023

Stars end their lives in a variety of ways. Low mass stars puff off their outer layers and settle down to become white dwarfs while massive stars end their lives in spectacular supernova explosions. A long hypothesized way for stars to end their lives by collisions of stars or stellar remnants in the densely packed area near a galaxy’s massive black hole. Andrew Levan recently found evidence of this new phenomena while following up a long gamma ray burst. In this podcast, Andrew Levan describes how a variety of telescopes provided the first evidence for this new way for a star to end its life.

Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Andrew Levan is a professor at Radbound University in the Netherlands where he studies astrophysical transients such as Gamma-ray bursts, supernovae, tidal disruption events and most recently the electromagnetic counterparts to gravitational wave sources.

Dear Cheap Astronomy Ep. 94: Things Can Only Get Bigger Jul 06, 2023

We enlarge upon enlargement.

– Why did the Universe inflate?

To coin a phrase, in the beginning there was inflation. Within a tiny fraction of the first second, the volume of the universe expanded exponentially, apparently by a factor of 10 to the 78th power – equivalent to something of one nanometer in length expanding to nearly 11 light years in length. This is not to say the early Universe had a radius of 11 light years at the end of inflation. We don’t really know how big the Universe was then, since we don’t really know how big the Universe is now.

– Why does the Universe expand?

Here at CA we think is the question that everyone should be asking – that is why, rather than how is the Universe expanding. The question of how the Universe is expanding is generally answered with the waffly concept of dark energy – even though dark energy was brought in fairly recently when it became apparent the Universe’s expansion had been accelerating over time. It was as though everyone had been OK with the idea that the Universe was steadily expanding, but as soon as we knew the expansion was accelerating we needed to conjure up a mysterious force to explain it.

The Daily Space - Several Kepler Planets Turn Out to be Small Stars Jul 05, 2023

Using updated stellar measurements based on new data from the Gaia mission, three (and possibly four) Kepler exoplanets are actually small stars, but it’s unlikely new calculations will reveal many more such issues. Plus, Ingenuity, astronauts, permafrost, and This Week in Rocket History, we look back at STS-3 and the first use of the Canadarm.

Astronomy Cast Ep. 687: Prepping for the Moon Jul 03, 2023

https://www.youtube.com/watch?v=mdMalbhkDfU

Streamed live on Jun 19, 2023.

We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay. But this will be different than the Apollo era, going to the scientifically fascinating, and difficult southern pole of the Moon. What needs to be done to prepare the way back to the Moon?

Actual Astronomy - Objects to Observe in July Jun 29, 2023

Ep. 342 is hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

Shane’s Observatory Construction has begun! The first step was for the builder to dig a hole for me to put all my money in…just kidding, that’s for the pier. We went down 40 inches and hit a boulder, good news since that’s as far as we planned to dig and it’ll make a solid footing. The soil was exceptionally dry despite the rain and should therefore keep water from collecting around the post.

M4 is a globular cluster in the constellation Scorpius, at magnitude 5.6 it is very bright but due to it glides low over the southern horizon from Canada.

M4 was discovered by Philippe Loys de Cheseaux in 1746, and included in Lacaille's catalogue. Charles Messier catalogued it in 1764, that's where it gets the "M'' designation and was the first to resolve it into a "cluster of very small faint stars." M4 was the only globular cluster Messier could resolve with his modest instruments, and thus the first globular cluster to be resolved.

Astronomy Cast Ep. 226: Weather Jun 26, 2023

Streamed live on March 28, 2011.

How’s the weather? Maybe a better question is… why’s the weather? What is it about planets and their atmospheres that create weather systems. What have planetary scientists learned about our Earth’s weather, and how does this relate to other planets in the Solar System. What is the most extreme weather we know of in the whole Universe?

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- An asteroid is exiled to the outer regions of the solar system during Jupiter's rampaging tack away from the Sun long ago. During that process enough material was left in Jupiter's wake to form Venus, Earth, Mars, and the asteroid belt as we know them today.

- The recent discovery of an asteroid, whose orbit lies completely within that of the Earth, reminds asteroid hunters to continue to search near the Sun so that a large dangerous object does not sneak up undetected on the residents of planet Earth.

Guide to Space - What is the Biggest Star in the Universe? Jun 23, 2023

https://www.youtube.com/watch?v=wtSNDjDw6fI

From May 13, 2013.

In this short explainer video, Universe Today's publisher Fraser Cain researches what is the biggest star in the Universe, as well as the most massive star, and explores the limits that stars can reach.

Based on this article in Universe Today

https://www.universetoday.com/13507/what-is-the-biggest-star-in-the-universe/

My six-year old daughter is a question-asking machine. We were driving home from school a couple of days ago, and she was grilling me about the nature of the Universe. One of her zingers was, “What’s the Biggest Star in the Universe”? I had an easy answer. “The Universe is a big place,” I said, “and there’s no way we can possibly know what the biggest star is”. But that’s not a real answer.

Astronomy Cast Ep. 686: Ice In The Shadows Jun 19, 2023

https://www.youtube.com/watch?v=9EDEcCRGaoo

Streamed live on Jun 12, 2023.

The permanently shadowed craters on the Moon are the focus of so much research. That’s because they seem to contain vast reserves of water ice. Water we could use for oxygen, propellant and so much more, but also, to help us understand where the Earth’s water came from.

Travelers in the Night Eps. 683 & 684: Tess & Our View Jun 18, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- To find planets close to home NASA has launched TESS the Transiting Exoplanet Satellite which will monitor more than 200,000 nearby, stars over the entire sky to detect the tiny dips in light caused when a planet passes in front of it's star. The TESS era will be a most exciting time as humans discover and are able determine the properties of relatively nearby habitatable worlds and dream about what might be living in our neighborhood of the Milky Way.

- Modern technology provides us with stunning views of objects in the Universe in wavelengths invisible to our eyes, however, nothing is as moving and thought provoking as looking into deep space with your very own eyes.

UNAWE Space Scoop - Watch Out, Earth! A Dying Star Just Ate A Planet Jun 16, 2023

https://spacescoop.org/en/scoops/2312/watch-out-earth-a-dying-star-just-ate-a-planet/

For the first time astronomers found direct clues of a dying sun-like star eating an exoplanet. The star is in the constellation Aquila, the Eagle, and is called ZTF SLRN-2020, but for now let’s just call it 2020. So much easier to remember!

Using the NSF NOIRLab’s Gemini South Telescope in Chile, researchers observed a long burst of light coming from the star, a burst low in energy. This is a telltale sign of a planet skimming along near the star's surface. This ‘long & low’ stellar outburst took place in our Milky Way nearly 13,000 light-years away from Earth.

Such events are estimated to occur at most only a few times each year and maybe only once a decade, across the entire Milky Way galaxy. So should planets like Mercury, Venus and Earth be worried?

Let’s find out!

Actual Astronomy Ep. 333 - Carbon Stars With Luca Vanzella Jun 15, 2023

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

Bio: Luca Vanzella has been an avid amateur astronomer since 1975, when he purchased his first telescope, a classic orange-tube Celestron 8″ SCT. Since then, he has been mainly an observer, avid skyscape shooter, and sometime eclipse & transit chaser. As an observer, Luca worked his way through the Messier and Finest NGC lists, with a special interest in globular clusters. In March 2016, Luca completed his first Messier Marathon. Luca has since completed the Astronomical League's Double Star list, Multiple Star list, the Herschel 400 list and is currently slogging, er... working through the Herschel II list. In 2016, Luca published the Carbon Start Hunter List.

Luca joined the RASC Edmonton Centre in the mid-1970’s and was a member for a few years. University and work life caused a long hiatus from the RASC (but not the hobby), until the year 2000 when he rejoined the Society. Since then, Luca has served the Edmonton Centre in various capacities, including schlepper, volunteer, General Assembly organizer, outreach event coordinator, secretary, national council rep, webmaster, vice-president and president. Luca is currently on the team building the Black Nugget Lake Observatory - Edmonton Centre's dark sky facility that will feature a 32" telescope.

Folklore - The Story of Corona Borealis: The Pot Star From Bali Jun 14, 2023

Hosted by Avivah Yamani, our Director.

Today I will share a story from Bali, Indonesia about Corona Borealis. The story is part of the Stars of Asia Project during the International Year of Astronomy in 2009 and compiled by Mitsuru Aoki from Japan.

Corona Borealis is a small constellation in the Northern Celestial Hemisphere. The constellation has only four stars brighter than magnitude 3 and form a semicircular arc . It was first cataloged by the Greek astronomer Ptolemy in the 2nd century and remains one of the 88 modern constellations. Its Latin name for the constellation is “the northern crown” inspired by its shape, In classical mythology Corona Borealis generally represented the crown given by the god Dionysus to the Cretan princess Ariadne and set by her in the heavens. Corona Borealis, the crown constellation, looks very different depending on where it is observed. When seen from Japan, it shines around the zenith in a “u” shape, when observed from Indonesia/Bali, the constellation appears in the North in a “n” shape, and for people in Bali, Indonesia, this constellation is known as a dented, upside-down cooking pot. It is said the Indonesian description originates from the actions of a careless and greedy couple…

Cheap Astro: Dear CA Ep. 93 - Spacecraft Jun 13, 2023

Crafting Spacecraft!

- What are the Parker probe and other spacecraft learning about the Sun?

The Sun is 99.9% of the entire mass of the solar system, weighing in at 1.9 times 10 to the 30th kilograms and if you think you can comprehend how much that is, you’re kidding yourself. Let’s just say it’s freakingly hugely massive, though on a universal scale, it is a fairly unremarkable G-type star positioned towards the lower end of the OBAFGKM range of stellar classes.

- Will there really be spacecraft that can travel in deep space but can also land on planets?

Probably the best examples of fictional deep space craft that can also land on planets are found in the Star Wars franchise, where most spacecraft seem to be both able to land and zip between stellar systems via hyperspace, whatever the heck hyperspace is.

Travelers in the Night Eps. 681 & 682: 17,000 To Go & Falling Space Rocks Jun 11, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- So far asteroid hunters have discovered about 8,000 of the 25,000, large, potentially hazardous asteroids, suspected to exist, leaving 17,000 more to be found. For this reason, NASA has designed and proposed the NEOCam spacecraft to give us the ability to find them before they find us.

- In the early evening of January 17, 2018 six hundred and seventy four observers in 11 States and Canada reported a fireball meteor streaking across the sky to the American Meteor Society. To find freshly fallen meteorites visit the American Meteor Society's website but do not hunt for meteorites on private land without permission.

NOIRLab - The Completion Of The Rubin Observatory EPO Program Jun 10, 2023

The Vera C. Rubin Observatory is currently under construction in Chile. The Rubin Observatory will scan the entire night sky visible from its location every 3-4 nights resulting in a massive amount of astronomical data.

The Rubin Observatory’s Education And Public Outreach (EPO) program recently launched. In this podcast, Dr. Stephanie Deppe tells us about the Rubin EPO program, resources currently available and gives a glimpse at what to expect when data starts flowing from the Rubin Observatory.

Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Stephanie Deppe is the Astronomy Content Strategist for Vera C. Rubin Observatory, where she creates online content for the observatory's social media and other internet presences. In a past academic life, she worked with telescopes in Chile to discover and study new icy asteroids orbiting the Sun beyond Neptune. When she's not talking about astronomy to anyone who will listen, you can find her on a mountain trail somewhere, reading a sci-fi book, or hanging out with her cat.

Streamed live on May 29, 2023.

One of JWST’s top jobs is to peer deeper into the Universe than ever before, watching as the first galaxies came together. Surprisingly, astronomers found galaxies that seemed much more mature than expected, much earlier than it was believed possible. What’s going on and what does it mean for cosmology?

Today's 2 topics:

- When Asteroid Hunters find a relatively large asteroid on a collision course with planet Earth, the challenge is to change its path to make it miss our home planet.

- If you set your mind to it, you can find and hold a sample of an asteroid, called a meteorite, which has landed on the Earth's surface. On the other hand, watching major meteor showers will allow you to see but not touch comet dust as it enters and burns up in the Earth's atmosphere.

Observing With Webb - June Episode Jun 03, 2023

Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night.

Venus shines bright at sunset all month, with Mars nearby, while Saturn, Jupiter, and even Mercury shine in the mornings, and the Beehive Cluster gets two wandering guests, all in the solstice month of June.

21st – Summer Solstice – This is the longest day of the year in the Northern Hemisphere.

Spring Constellations: Big Dipper, Boötes, Virgo, Corona Borealis, Hercules – Gaze almost vertically as you face the NW, and you’ll easily find the Big Dipper: seven very bright stars that form a saucepan shape. Now if you take the handle of the Dipper, follow its curve to the next bright star you see, about 20˚ away, which is Arcturus. “Follow the arc to Arcturus.” That’s the brightest star in Boötes, which looks like a kite.

Take that same curve, and follow it about another 20˚ to “South to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid. Now go back to Boötes, and just to the left of Boötes are seven stars that form the northern crown Corona Borealis, which looks more like a small bowl or a “C” in the sky.

Continue a little further to the left and you’ll find the keystone asterism which is part of the constellation Hercules. Extra Challenge! Look for M13, the Hercules Cluster in between two of Hercules’ “keystone” stars. It known as the best globular cluster in the northern skies. It will be a fuzzy spot in binoculars and will be even cooler through a telescope.

Actual Astronomy Ep. 330: Objects to Observe in June Jun 01, 2023

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

We’re recording this early, in fact I’m writing these notes up on May 5th! That’s a record for us but we’re both away on alternating weeks so when the bright naked eye comet is shining overhead this month and you’re wondering why we didn’t mention…this is why.

June 1st - Venus, Castor and Pollux in a line

Mars is making its way through M44 during the first few nights this month.

June 3rd - Full Moon

June 4th - Venus is at greatest elongation 45-degrees from the Sun this evening

June 6th - Asteroid 11 Parthenope is at opposition, m=9.3

Parthenope was discovered by Annibale de Gasparis on 11 May 1850 and named after Parthenopē, who was one of the Sirens of Greek mythology, said to have founded the city of Naples. It orbits the Sun every 3.84 Earth years and has a rotation period of 13.7 days and 153 km in diameter.

June 10th - Last Quarter Moon paired with Saturn for those much farther east

June 13th - Venus near Beehive

June 14th - Jupiter 1.5-degrees to right of Moon in morning twilight. (4-degrees SK)

June 16th - Take this Friday off so you can stay up all night Thursday.

20 Massalia at opposition 9.9 mag.

Discovered by Italian astronomer Annibale de Gasparis on 19 September 1852, it was named for the French city of Marseille, from which the independent discoverer Jean Chacornac sighted it the following night. A stony asteroid and the parent body of the Massalia family of objects located in the inner region of the asteroid belt. It is about 145 kilometres in diameter. Takes 3.74 years to orbit Sun.

June 18th - New Moon

June 21st - Summer Solstice

Great Triangle - Mars, Venus & Moon

June 26th - First Quarter Moon & Lunar Straight Wall Visible - Image from Jim

June 28th - Venus & Mars ~3.5 degrees apart

No bright comets. :^(

UNAWE Space Scoop - Fast & Furious Starring Dual Quasars May 30, 2023

https://spacescoop.org/en/scoops/2311/fast-and-furious-starring-dual-quasars/

Astronomers describe 'cosmic noon' as a dramatic period in the history of our Universe when it was buzzing with galaxy mergers and furious star formation.

Observing these mergers has been relatively rare and challenging, since the Universe was very young back when the mergers were happening. The Universe was only three billion years old then, so this was about 7 billion years ago.

Taking a look at how over the last 40 years we went from only knowing of the handful of planets in our solar system to knowing of around 5,000 planets littering the galaxy.

- How have we discovered new planets?

- How many are there?

- How many stars have planets around them?

- Are there star systems with multiple planets like our solar system?

- Do we see the diversity of large gassy, small rocky and ringed planets around other stars?

… And the big one:

- Are any of them habitable?

Find out in this episode!

Astronomy Cast Ep. 682: Ultra-Diffuse Galaxies & Dark Matter May 22, 2023

https://www.youtube.com/watch?v=ta9lH755xw0

Streamed live on May 15, 2023.

Astronomers first noticed the strange behaviors of rotating galaxies almost 100 years ago, suggesting there’s an invisible dark matter hold them together with gravity. Or maybe we just don’t understand how gravity works at the largest scales. Observations are much better now, and astronomers have found examples of galaxies that are almost entirely made of dark matter. Does this tell us anything?

Travelers in the Night Eps. 675 & 676: Nuking An Asteroid & Cloud 7 May 21, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Tonight, even though the chances are extremely slim, an asteroid hunter could find a sizable asteroid on a collision course with planet Earth. If we have decades warning, the potential impactor's arrival time could be changed by impacting the dangerous object with a high velocity mass or if we have less time we will need to nuke it which will either blow it to bits or give it a rocket like push.

- To give you an idea of the asteroid traffic in our neighborhood, on a mostly cloudy night, through holes in the clouds, in a space of less than 2 hours, my Catalina Sky Survey teammate Richard Kowalski posted 7 new close approaching asteroid discoveries on the Minor Planet Center's Near Earth Object Confirmation Page.

Paul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host.

Damien Phillips, John Wildridge and Dustin Ruoff produce.

To mark the Skylab 50th anniversary here is one our favourite astronaut chats from 2012 where we caught up with Skylab 3 and STS-3 astronaut, Jack Lousma. Jack was also capcom during Apollo 13 and he tells us about taking that ominous ‘Houston, we’ve had a problem’ call and how they solved each life-threatening issue in sequence to get the astronauts back alive. He talks about missing out on flying Apollo 20 to the moon, being a crew member on the Skylab space station and taking one of the first space shuttles out for a test drive.

Actual Astronomy - Observing and Sketching With Dr. Berta Beltran May 18, 2023

Episode 323.

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

Bio: Berta Beltran is a visual observer from Edmonton Alberta where she sketches mostly from her backyard or a dark cemetery site when time is available. Berta has a PhD in particle Physics and has worked at CERN. Currently working on a Nutrino project. She also works as an Outreach Assistant at the University of Alberta. Berta sketches everything she sees through her telescopes, from the Sun, Moon and Planets to Deep Sky Objects and Comets. We have been having a knowledge exchange where she has been providing me advice on some new sketching tools and techniques while bouncing some telescope ideas off us as she pursued a new refractor. So I thought, heck let’s just bring you on the show and have a proper chat.

Astronomy Cast Ep. 681: Kilonovae May 15, 2023

https://www.youtube.com/watch?v=bOOfgvvPbZc

Streamed live on May 7, 2023.

In 2017, astronomers detected the gravitational waves and electromagnetic radiation from colliding neutron stars. This had been long theorized as one of the causes of a certain type of gamma-ray burst. By studying the event and its afterglow, astronomers have learned a tremendous amount about the formation of the heaviest elements in the Universe.

Travelers in the Night Eps. 673 & 674: Christmas Comet & Asteroid Homestead May 14, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- On December 25, 2017, while searching for Earth approaching asteroids in the constellation of Virgo, the Universe gave my Catalina Sky Survey teammate Greg Leonard a Christmas present in the form of a comet which now bears his name: P/2017 Y3 (Leonard).

- In the future one can envision a space mining family boarding a descendent of the SpaceX Falcon Heavy Launch Vehicle for a trip into low Earth orbit. A few hundred miles above the Earth's surface they would rendezvous with their asteroid mining spacecraft which will be their home for the next five years or so.

NOIRLab - Catching A Star Devouring A Planet May 13, 2023

By studying countless stars at various stages of their evolution, astronomers have been able to piece together an understanding of the life cycle of stars and how they interact with their surrounding planetary systems as they age.

This research confirms that when a Sun-like star nears the end of its life, it expands anywhere from 100 to 1000 times its original size, eventually engulfing the system’s inner planets. Such events are estimated to occur only a few times each year across the entire Milky Way. Though past observations have confirmed the aftermath of planetary engulfments, astronomers have never caught one in the act, until now.

Bios:

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Dr. Kishalay De is a NASA Einstein postodoctoral fellow and (subsequently) MIT Kavli Institute postdoctoral fellow at the Massachusetts Institute of Technology. Kishalay works with wide-field imaging surveys on the ground and in space to discover cosmic fireworks from stellar binaries in our Galaxy and in the distant Universe. Using panchromatic follow-up facilities, he tries to understand the role of stellar cataclysms in shaping the unvierse as we "see" it in light and "hear" it in gravitational waves.

Kishalay obtained his PhD in Astrophysics from the California Institute of Technology in 2021, under the supervision of Mansi Kasliwal. As part of his thesis, he served as the data pipeline lead and helped commission Palomar Gattini-IR, the first wide-field infrared time domain survey to study dust obscured eruptions in the Milky Way. Using the Zwicky Transient Facility wide-field optical time domain survey, he helped construct the largest volume-limited sample of nearby supernovae to study faint and fleeting explosions from the eruptions of helium shells on white dwarfs and births of neutron stars in compact binary systems. Previously, Kishalay obtained my undergraduate degree in Physics from the Indian Institute of Science in 2016, working with Yashwant Gupta and Prateek Sharma on high time resolution studies of radio pulsars.

Cheap Astronomy - Dear CA #92: Sex in Space! May 11, 2023

Things that make you go hmmm.

How bad is gender bias in space?

In a perfect world, special consideration of women in space would be unecessary. There would just be consideration about generic humans where we might ponder a range of physical differences.

Can you, you know, get it up in space?

In terms of the sheer mechanics involved, the key point here, at least for the male half of the equation, is whether can you get it up in space. This is not to discount the vitally important role played by women in the overall transaction, but if the guys can’t get it up, the rest of the process does become a bit problematic.

Astronomy Cast Ep. 680: Rogue Black Holes May 08, 2023

https://www.youtube.com/watch?v=ZprHwGHUARU

Streamed live on May 1, 2023.

Last week we talked about rogue stars. This week we’re going to take things up a notch and talk about an even more extreme event. Rogue black holes. Astronomers recently discovered a supermassive black hole on an escape trajectory, leaving newly forming stars in its wake. It’s wonderful, terrible, nightmare fuel.

Fraser’s rogue SMBH article:

Travelers in the Night Eps. 671 & 672: Long Winter’s Nights & Meteor Whispers May 07, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Long Winter nights with good seeing, from start to finish, are those on which the asteroid hunter makes new discoveries while being treated to views of millions of stars, gas clouds, and galaxies which inspire a child like sense of wonder.

- Recent scientific studies have begun to shed light on the interesting mystery of how the small number of what we now call electrophonic meteors produce simultaneous light and sound. If you are lucky you could hear a meteor's dying whispers and could even be the first person to record these sounds on your cell phone.

Streamed live on Apr 24, 2023.

Most stars in the Milky Way are trapped in here with us, doomed to orbit around and around and around. But a few have found a way out, an escape into the freedom of intergalactic space. How do stars reach escape velocity, never to return?

Travelers in the Night Eps. 669 & 670: Seeds (356) & Laser Surfing (364) Apr 30, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life.

- When we find a planet which appears to have the chemical signs of living organisms in its atmosphere, the desire to take a close up look at it will be hard to contain. Laser propelled ultra light space probes could be sent to explore nearby worlds. The cost of investigating our planetary life hosting neighbors is likely to be less than what the US is planning to spend upgrading its nuclear weapons.

UNAWE - Playing Connect-the-dots Around A Baby Star Apr 29, 2023

https://spacescoop.org/en/scoops/2309/playing-connect-the-dots-around-a-baby-star/

Have you ever played a connect-the-dots game?

At first, it looks like a mess. But after you start to connect the points, a pattern appears out of the chaos. Recently, astronomers noticed a mysterious spiral pattern hiding around a baby star. But instead of dots, the pattern was made up by a strange kind of physics phenomenon called masers!

Awesome Astronomy - Searching for ET & Aliens in Space Apr 27, 2023

https://www.youtube.com/watch?v=tL5SQyELuJ4

Paul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host.

Damien Phillips, John Wildridge and Dustin Ruoff produce.

From Feb 11, 2022.

Are we alone in the cosmos? Do aliens exist? How are we looking for them? And how long will it be before we know for sure?

Well, we're searching every corner of space for alien microbes or signals from ET.

From the Viking lander that found hints of life on Mars and the #SETI Institute's 'Wow signal' to #JWST and Europe's Extremely Large Telescope, we run through the serious scientific attempts to find ET in our solar system and beyond.

Cheap Astronomy - Dear CA #91: Supernovae. Again. Apr 26, 2023

Things that make you go kablooie.

Why do supernovae explode once they start fusing iron?

Right now our Sun is fusing hydrogen into helium in its core. In maybe five billion years the situation will be all clogged up when the core has become mostly helium and the hydrogen fusion happens around it in a fusion shell.

What are binding energies?

Technically speaking a binding energy is the amount of energy required to disassemble a system of particles. So it’s actually a measurement of the amount of energy required to overcome the forces that bind particle systems together.

The Daily Space - Hubble Discovered A Star Hidden By Companion’s Supernova Apr 25, 2023

From May 6, 2022.

Data from the Hubble Space Telescope has determined that the newly discovered companion of a star that went supernova had its outer hydrogen layer siphoned off before the explosion. The results support the theory that massive stars generally form and evolve as binary systems. Plus, rocks from space, Crew-4 comes home, searching for life beyond Earth, and another Canon lens review.

The Cosmic Savannah Ep. 43: The Search For Hidden Hydrogen Apr 22, 2023

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

In this episode we are joined first by Dr. Tariq Blecher and then by Shilpa Ranchod who talk to us about the clever ways they are trying to capture the elusive signals of hydrogen gas in the distant Universe.

Hydrogen is one of the most common elements in the Universe and this gas is one of the fundamental building blocks of galaxies. Yet the radio signal released by hydrogen gas is very faint, and so is notoriously difficult to detect.

Tariq and Shilpa, who are colleagues, are both trying to pry open the secrets of hidden hydrogen in the distant Universe by using very clever strategies. Tariq was recently awarded his PhD from Rhodes University and he joins us to explain some of his thesis research.

He tried to make the first detection of hydrogen with “gravitational lensing.” He tells us that giant galaxies and clusters can act as cosmic lenses to magnify the signals from very distant galaxies behind them. If successful, this technique could help us understand more about galaxy evolution and dark matter.

We are then joined by Shilpa Ranchod who recently completed her MSc at the University of Pretoria. Shilpa is also searching for hydrogen signals using gravitational lensing. She uses South Africa’s powerful MeerKAT telescope, combined with another clever technique called “stacking.”

Shilpa was also recently in the press for her discovery of an entire group of galaxies hiding in plain sight! This galaxy group likely contains more neutral hydrogen gas than most groups ever discovered!

The galaxy group was discovered by the MeerKAT International Gigahertz Tiered Extragalactic Exploration (MIGHTEE) survey. MeerKAT strikes again!

Actual Astronomy - Large Aperture Telescope Observing and Sketching with Howard Banich Apr 21, 2023

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

Today we are joined by Howard Banich. Howard has been observing the night sky since 1966 and soon began building telescopes when he was only 14! A long time member of the Rose City Astronomers and frequent attendee of many star parties and for those of us who subscribe to Sky & Telescope magazine we know Howard as a passionate writer, observer and sketcher. In our correspondence I’ve found that Howard is like many of us as he is always seeking out new targets and new ways of appreciating the night sky we all love.

UNAWE Space Scoop - A Supernova Coming Back to Life Apr 20, 2023

https://spacescoop.org/en/scoops/2308/a-supernova-coming-back-to-life/

For only the second time, astronomers saw a supernova light up again. Strange, since the brightness of supernovae fades away in a couple months. An international team of researchers from Kyoto University and Osaka University were looking at SN 2018ivc using the ALMA Observatory, the Atacama Large Millimeter/submillimeter Array in Chile, and found something unusual.

- By the way, the SN in SN2018ivc stands for supernova.

SN 2018ivc, located in the galaxy M77, appeared to dim 200 days after the initial explosion and began to light up again 800 days later.

- Also by the way, the M in M77 stands for Messier.

NOIRLab - Galactic Immigration in the Andromeda Galaxy Apr 08, 2023

Galaxies grow through mergers with other galaxies. Astronomers can uncover evidence of this in our galaxy by mapping the motions of stars. Using the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall Telescope at Kitt Peak National Observatory, astronomers have studied the merger history of the Andromeda Galaxy for the first time. In this podcast, Dr. Joan Najita describes this study and what we have learned about the immigration history of the Andromeda Galaxy.

The Daily Space - Found: Metal-rich Star. Parents Being Sought Apr 07, 2023

From May 11, 2022.

A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-82 (84).

Cheap Astronomy - Dear CA Ep. 90: Space Exploration on Paper Apr 05, 2023

Next steps, maybe.

How likely is a space way-station like Deep Space 9?

So, anything is possible, but what is likely is what is economically feasible. In other words, while you could have a deep space way station like Deep Space 9, there’s has to be a need for it. So, for example here on Earth there’s no deep Sahara desert or a deep Congo jungle bases, but there are deep Antarctica bases, indeed several of them.

Are there still plans for a crewed asteroid mission?

Well, not really. There’s probably still lots of people still thinking about such a mission, but there’s nothing that’s in any respect scheduled, at least for NASA and as far as we know.

Streamed live on Mar 27, 2023.

Ice is ice, right? You know, what you get when water freezes. Well, maybe here on Earth. But across the Universe, water can be squeezed together at different temperatures and pressures, leading to very different structures. Today we’ll talk about the different forms that ice can take.

Observing With Webb - April Episode Apr 01, 2023

Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night.

Venus shines bright all month, Mercury makes a 3 week appearance, Mars hangs out with Gemini, Saturn continues its morning planet season, and the Lyrids have excellent observing conditions.

April 22nd: LYRID METEOR SHOWER – At only 10-20 meteors per hour, it is a minor shower, but we have essentially no Moon to get in the way of the best observing. The shower is greatest on the 22nd, but you might see some on the 21st and 23rd as well. Just remember each meteor is piece of debris left over from a comet, and we’re crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. The best viewing is between 2am and 4:30am, but you never know when you’ll see something awesome.

Some advice for watching:

- Find a dark location and lie down in a reclining chair or something that insulates you from the ground.

- Check the weather to see if the skies will be clear.

- Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.

- If you’re feeling extra nerdy, do a scientific meteor count (S&T and IMO)!

Guide To Space - The Problem of Power in Space. NASA's New Kilopower Reactor Mar 31, 2023

https://www.youtube.com/watch?v=m2IiI4UVZP8

From Jun 8, 2018.

Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention all the power to run scientific instruments and the transmitters to send that data home.

Getting enough power in space is a big problem.

Cosmic Savannah - Ep. 42: Rockin’ All Over the World Mar 25, 2023

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

In this week’s episode, we take a deep dive into how a planet (in this case Earth) is constructed! We are joined by Dr. Eugene Grosch who is a geologist and petrologist at Rhodes University in South Africa. Eugene discusses his work on some of the oldest rocks in the country and what we can learn from them.

We learn about how precious metals and diamonds are created and moved through the Earth’s crust. We also discuss how planets create the building blocks for life, and how life, in turn, helps to create the minerals we find on Earth!

Guide to Space - What Do We Do With Aging Spacecraft? Mar 24, 2023

https://www.youtube.com/watch?v=mWg3Jby9lBA

From Jan 3, 2018.

We try to avoid thinking about it, but spacecraft are machines that break down and eventually fail. Some can last for years, others decades, but in the end they’ll be gone forever.

Space agencies do consider how these missions will end, and put plans in place to wrap them up when the time comes. But sometimes they have no choice, and dead spacecraft return to Earth with no way of controlling when and where it’s going to happen.

UNAWE Space Scoop - High Speed Baby Star Tantrums Mar 21, 2023

https://www.spacescoop.org/en/scoops/2304/high-speed-baby-star-tantrums/

Baby stars form when thick clouds of gas and dust fall into themselves or collapse due to gravity. Not all of the material collapses to form a baby star.

A new study shows that some gas can escape at a high speed, which astrophysicists call a high-speed outflow. Because most stars form in large groups, theory predicts that some of these high-speed outflows of gas, coming from a star-forming cloud, can mix with another cloud nearby. This mixing can possibly affect the star formation in the nearby cloud.

Travelers in the Night Eps. 657 & 658: Plant Companionship & Fireball II Mar 19, 2023

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- The plants that Mars explorers take with them will provide a source of fresh fruits and vegetables, fresh air to breathe, and perhaps a psychological benefit that is crucial to the success of their mission.

- Recently there were four fireball meteors, brighter than the planet Venus, which exploded over Germany, France, Ohio, and Arizona within the space of only 10 hours. There are likely to be on the order of 1,000 fireball events over the Earth every day.

Deep Astronomy - How “Many Worlds” Quantum Mechanics is Like Intelligent Design and Sets a Dangerous Precedent Mar 18, 2023

https://youtu.be/sQbB1JduTOo

From Oct 31, 2019.

Is the many-worlds interpretation of quantum mechanics science? While we may not be able to say what exactly science is, I can say that I prefer to have my science with a little bit of data. For me to recognize science when I see it, it has to come with some observations or something verifiable. But hey that’s just me, and apparently I’m in the minority on this issue.

You may very well ask, oh c’mon what’s the big deal? Who cares if a bunch of cosmological Poindexters write some papers that only get read among themselves, that have a bunch of math in it and have no practical value to us at all.

Guide To Space - Just How Tough Is Earth Life? Tough Enough To Go Space And Still Thrive Mar 17, 2023

https://www.youtube.com/watch?v=xiJdxTzw2Dg

From Jun 4, 2019.

Every time we send a spacecraft to another world, our Earth-based lifeforms are going with us. No matter how well we try to keep them clean, a few stowaways will always come along for the ride.

You’d think that years in the cold hard vacuum of space, suffering extreme temperature changes, and receiving brutal doses of radiation would be all it takes to sterilize any life caught on the outside of a lander or rover headed to Mars or Europa.

Well, think again. Life just demonstrated that it’s surprisingly ready to make the journey, and happy to get back to work the moment conditions improve.

The Daily Space - Found: Metal-rich Star. Parents Being Sought Mar 15, 2023

From May 11, 2022.

A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-82 (84).

NOIRLab - The First Kilanova Progenitor Mar 11, 2023

Kilonovae form when two neutron stars collide. They were first discovered by their gravitational wave emissions. In this podcast, NOIRLab’s Dr. André-Nicolas Chene described the discovery of a system that will become a kilonova in the future.

Bios:

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona..

André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini's user support effort. André-Nicolas’s research interests are massive stars, hot winds, star clusters, and stellar evolution.

Guide to Space - Living Off The Land On Mars Mar 10, 2023

https://www.youtube.com/watch?v=zmpQpmhigEY

From Dec 10, 2019.

Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. And unless there are dramatic discoveries in new propulsion systems or we learn how to build everything out of carbon nanotubes, the future of space exploration is going to require living off the land.

The technique is known as In-Situ Resource Utilization or ISRU, and it means supplying as much of your mission from local resources as possible.

And many of our future exploration destinations, like Mars, have a lot to work with. Let’s look at the raw materials on Mars that missions can use to live off the land and the techniques and technologies that will need to be developed to make this possible.

Awesome Astronomy - Predicting Supernovae Mar 09, 2023

https://www.youtube.com/watch?v=ZYLtwPRhnU8

From Oct 21, 2022.

Hosted by Ralph Wilkins. Damien Phillips, John Wildridge and Dustin Ruoff produce.

This show is all about Betelgeuse and supernovas (supernovae? Let's call the whole thing off).

What will happen to Betelgeuse? How bright will it get? When will it go supernova? Will we get to see it? How do we predict supernovas?

A new study points to a rapid dimming (like the one we saw in 2019!) just before it obliterates itself in a violent release of energy that will make it brighter than anything else in the night sky.

But please do help us out by subscribing to the channel, if you don't already:

The Daily Space - Plants Successfully Grown in Lunar Soil Mar 08, 2023

Using a mere twelve grams of lunar soil returned by the Apollo missions, scientists have successfully grown plants in the lab. With a wealth of genetic data on hand, they can now analyze the changes to the plants and the soil. Plus, stellar cannibalism, a black hole merger, brown dwarfs, water on Mars, and a review of “Star Trek: Strange New Worlds”.

Observing With Webb - March Episode Mar 04, 2023

Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night. Venus is bright all month, Jupiter disappears, Mars hangs out with Taurus, Saturn begins its morning planet season, and Mercury peaks in for a taste of the action toward the end of the month.

20th – Spring Equinox - Astronomically the first day of Spring, even though meteorologically Spring starts in the beginning of March. Here’s some more info.

22nd – 24th – CLOSE ENCOUNTER – Moon, Jupiter, Venus – On the evening of Wednesday the 22nd, look West right after sunset. You’ll likely see Venus first, being very, very bright. About 20˚ below Venus will be a RIDICULOUSLY thin crescent Moon, with Jupiter just 1˚ to the right of the Moon. You’ll definitely need a clear horizon and skies for this one.

Have you ever wondered why fewer and fewer stars appear in the night sky, especially if you live in a city?

A recent study by NOIRLab’s educational project ‘Globe at Night’, shows how light pollution is increasing fast, taking away the majestic view of our starry night sky. Light pollution is a serious issue that has many harmful effects.

Actual Astronomy - Objects To Observe in March Mar 02, 2023

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

- This month starts off with a bang. Last night! March 1 (yesterday) featured a spectacular conjunction of Jupiter and Venus. So you missed that one.

- The zodiacal light is something you might see if you can go to a super dark site. It comes from dust that’s come from Mars.

- March 20th is the spring equinox.

- Ceres will be at mag 6.9, and March 20 is a fine time to try to see it. A planetarium software package like Stellarium will help you find it.

- There’s much, much more!

Cheap Astronomy - Dear CA #089: Spacecraft Feb 24, 2023

To Boldly Speculate…

Dear Cheap Astronomy – How would you design a spacecraft?

Here at Cheap Astronomy we’d use recycled materials, outsourced labour and lots of cut corners. Seriously though... if we’re talking about a crewed spacecraft one of the first things to think about is gravity.

Dear Cheap Astronomy – Are everything-you-launch-is-it spacecraft now old technology?

So, this is really a question about whether the Apollo mission concept – of launching everything in one go is the way of the future or will we move to an approach of where you launch components separately and then assemble them in orbit – and maybe fly to your destination where the various pre-launched modules are already positioned there awaiting your arrival – like say a Mars lander?

Ask A Spaceman Ep. 194: Does the Universe Rotate? Feb 21, 2023

How do we know that the universe doesn’t rotate? Why would it matter if it did? What does all this have to do with time travel? I discuss these questions and more in today’s Ask a Spaceman!

There’s a short audio problem at 20 minutes, 12 seconds that I can’t fix. I’ve left it in just in case you can make sense of it. “Not a blank check here, but it allowed to rotate the Universe.” Is one part of the audio. “We use artificial models all the time in physics that…” is another part. Mixed together such that I have trouble teasing out what he’s saying. I’m sure it was good stuff.

https://www.youtube.com/watch?v=LZOYKDGglo8

Streamed live on Feb 13, 2023.

The Universe was inaccessible for most of human history, but the first tentative steps to space in the 20th Century made humanity realize that science fiction was becoming science reality. New rules would have to be written to govern how we used this limitless expanse. Today we’ll talk about the Outer Space Treaty of 1967.

Guide to Space - Missing Baryonic Mass in the Universe… Found! Feb 17, 2023

https://www.youtube.com/watch?v=y0sCFM6w9f8

Streamed Jul 17, 2018.

Astronomers have finally solved one of the outstanding mysteries in cosmology. Forget about all the dark matter and dark energy, where’s all the missing regular mass in the Universe? This has been called the “missing baryon problem”.

They’ve been chipping away at the problem, finding missing matter in the vast gulfs between galaxies, and in the last few months, a team of astronomers have finally found the outstanding missing matter.

Actual Astronomy - Light Pollution With Rick Huziak Feb 16, 2023

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

Light Pollution with special guest Rick Huziak on Episode 299 of the Actual Astronomy Podcast.

Rick is most widely recognized as the face of SSSP (The Saskatchewan Summer Star Party) operating as lead organizer and registration tent ring leader for the past 27 years. He compiled the list of Carbon Stars in the RASC Observer’s Handbook. He has submitted over 180,000 variable star observations to the AAVSO and is a meteorite collector who appeared on such shows as Meteorite Hunters and helped in the recovery of some tonnage of the Buzzard Coulee meteorite fall here in Saskatchewan. In 2004 - International Astronomical Union named main-belt asteroid 4143 Huziak after him.

Rick has sat on the RASC National Light Pollution and Abatement Committee for several decades. Rick is well known for his work here which prompted the Saskatchewan Eco-Network to name Huziak a Saskatchewan Environmental Champion Oh and it’s thanks to Rick that we have the Grasslands National Park Dark Sky Preserve as he did much of the groundwork on the amateur astronomy side to have this the darkest dark sky park designated to protect it for years to come.

Astronomy Cast Ep. 669: Challenges to Dark Energy Feb 13, 2023

https://www.youtube.com/watch?v=5_1L_P24gT4

Streamed live on Feb 6, 2023.

It’s been over 20 years since astronomers first discovered that the expansion of the Universe is accelerating thanks to dark energy. And in these decades, astronomers still don’t have much evidence for what could be causing the increased expansion rate. Maybe there’s something else going on to explain it.

NOIRLab - Losing the Night Sky Feb 11, 2023

Light pollution has been impacting our view of the heavens for many years. Globe at Night is a citizen science campaign that invites people around the world to measure their night sky brightness and contribute data to the Globe at Night database. A recent paper based on Globe at Night data shows the night sky is brightening more than previously thought based on satellite measurements. In this podcast, Connie Walker and Christoper Kyba discuss this new research.

Bios:

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Dr. Christopher Kyba is a physicist who has been studying light in the outdoor environment since 2009. He works with data from many different sources, ranging from satellite observations and aerial photos to all sky imagery and observations with the human eye. He has led the development of a number of citizen science projects and tools, including Radiance Light Trends, the Loss of the Night app, My Sky at Night, and most recently the Nachtlichter (Night Lights) app.

Dr. Connie Walker is an astronomer at NSF’s NOIRLab in Tucson, Arizona USA. She has been working to abate light pollution in different ways regionally, nationally and internationally over the last 20 years. She has been involved with revising local lighting laws to holding conferences nationally and internationally to being on the International Dark-Sky Association Board of Directors (twice) to holding leadership positions at the International Astronomical Union (and helping to form a resolution on people’s right to starlight). The launching point was helping to create the international citizen-science program, Globe at Night, that asks citizen scientists to rate their night sky brightness which compares star charts with different numbers of stars to what they see in the night sky.

Guide To Space - Is There A Shadow Biosphere? Searching For Life On Earth That Isn’t Related To Us Feb 10, 2023

https://www.youtube.com/watch?v=2brd-3OVgn8

Premiered Jan 28, 2020.

Whenever I talk about the search for life in the Universe and its emphasis on water, I get comments that scientists aren’t being creative enough. Why does life rely on water? Couldn’t there be lifeforms which are completely different from life on Earth? Isn’t that the textbook definition of alien?

Astrobiologists have only scratched the surface in their search for life in the Universe, and they’re going after the low-hanging fruit. Since life on Earth can be found wherever there’s water, why not check out the water on other worlds? If that doesn’t pan out, then they’ll expand the search.

But it’s possible there are aliens living right here on Earth among us, in a shadow biosphere, we just haven’t detected them yet.

UNAWE - AI Reveals Black Holes and Galaxies Grow Up Together Feb 08, 2023

https://spacescoop.org/en/scoops/2223/ai-reveals-black-holes-and-galaxies-grow-up-together/

Astronomers recently found that the growth of a galaxy and the growth of the supermassive black hole, or SMBH, at its center have a lot in common.

By training a computer to study and model the data, the astronomers were able to confirm this decades-old theory. They’ve always been curious about how black holes form and grow.

Streamed live on Jan 30, 2023.

Astronomers have made extremely accurate measurements of the expansion rate of the Universe and come up with different results. And the error bars for the observations don’t overlap, so there’s something strange going on. What’s the answer and how can the Crisis in Cosmology be resolved?

Observing With Webb - February Episode Feb 04, 2023

Venus bright all month, Saturn disappears, Jupiter closes in on Venus, and Mars shines high and bright all month.

Naked-eye PLANETS:

Sunset

Venus – Look WSW after sunset. It’ll be low on the horizon throughout the month, but will be the brightest object and probably the first “star” you’ll see, and will get a little bit higher each night. Very close to Jupiter on the 28th.
Jupiter – SUPER bright in the WSW after sunset. Just find the brightest point of light in that direction (but not Venus), about 1/3 up the sky, and you’ve got it. Sets between 9:30pm and 8:30pm.
Mars – Look South and almost straight up, for a dull reddish dot in the sky, above Orion and around the extended right horn of Taurus.

Throughout the night

Mars – Look SW early in the evening, West around midnight. Sets at 3:30am at the beginning of the month, and 2:00am at the end of the month.

Morning

Mercury – Keep an eye out for Mercury in the early mornings just before sunrise. During the first week, Mercury will be easiest to spot right in the SE, but still very low and pretty dim, but brighter than any stars nearby. Find a good clear horizon and be patient.

Awesome Astronomy - February Part 1 Feb 01, 2023

Paul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host.

Damien Phillips, John Wildridge and Dustin Ruoff produce.

This is Ralph’s last show. :^(

The Discussion:

- Our dark sky practical astronomy event, AstroCamp.

- Farewell Apollo 7’s Walt Cunningham.

- Comet C2022 E3 ZTF reaches naked eye brightness.

The News:

Rounding up the astronomy news in February, we have:

- Incredible finding: stars have not always been made the same way throughout the history of the Universe.

- The debacle of the first space launch from UK soil. (With an absolutely epic rant from Paul!)

- 3 rocky water worlds found by the Kepler Space Telescope.

The big news story: A decade-long study finds light pollution is worse than we thought.

The Sky Guide:

This month we’re taking a look at the large winter constellation of Ursa Major with a guide to its history, how to find it, a few deep sky objects to seek out and a round-up of the solar system views on offer in February.

Q&A:

Does the James Webb Space Telescope have to take calibration frames like I do from Earth - darks, flats, and bias frames to then stack?

From our good friend Peter Coates in East Yorkshire.

http://www.awesomeastronomy.com

Bio: Awesome Astronomy is a podcast beamed direct from an underground bunker on Mars to promote science, space and astronomy (and enslave Earth if all goes well).

Cheap Astronomy - Dear CA Ep. 88: Things We’re Not Sure About Jan 31, 2023

– Can we terraform Venus?

Well maybe, though it would require some very advanced planetary engineering and huge amounts of energy. And whether you could then keep Venus terraformed without ongoing engineering interventions looks doubtful, although you could probably say the same for Mars terraforming plans.

– Please tell us more about standard candles!

As we’ve discussed before on Cheap Astronomy our understanding of the Universe is a bitsy construction, where we know what some bits are, but we don’t know other bits are – although we are pretty sure they are bits. The bits that we do know about only make up 5 per cent of all the bits – in other words 95 per cent of the Universe is composed of dark bits. And even then... the subject of this episode is to question our confidence about the 5% of the story that we think we know about.

The Cosmic Savannah Ep. 40 - The Mystery of the Fast Radio Burst Jan 28, 2023

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

In this episode, we speak with Dr. Marisa Geyer. She is a pulsar astronomer and Commissioning Scientist at the South African Radio Astronomy Observatory (SARAO) in Cape Town, South Africa. Marisa tells us what it’s like to be a commissioning scientist for the MeerKAT telescope. She also explains her research on pulsars and mysterious Fast Radio Bursts (FRBs). FRBs are sudden, bright flashes of radio light. Usually they only appear once and then are never seen again.

The mystery is that we don’t know what is causing these bursts of light! All we know is it’s something powerful, and probably something very far away.

Marisa talks us through the mystery and reveals some enticing clues about what might be causing FRBs. Hint: it involves something called a magnetar!

Guide To Space: Spacecraft Gyroscopes And Reaction Wheels. You Can Never Have Enough Jan 27, 2023

https://www.youtube.com/watch?v=mvVgGh7uiEg

From Aug 13, 2019.

It’s amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more.

And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel.

It’s all thanks to the technology of reaction wheels and gyroscopes. Let’s talk about how they work, how they’re different, and how their failure has ended missions in the past.

If you’ve never been to the southern hemisphere (or the northern hemisphere, if you live in the southern hemisphere), you might not be aware that the moon and the constellations appear upside down!

In this episode we’ll show you how that appears, why, and how that proves the Earth isn’t flat - as if any more proof were needed!

But please do help us out by subscribing to the show:

Deep Astronomy - The Closest Known Black Hole Jan 21, 2023

https://www.youtube.com/watch?v=SVkwkzES1DE

Oct 12, 2022.

No one knows how many black holes there are in the Universe. Black holes do not emit any light of their own making them impossible to see directly with telescopes. The only way we can detect black holes is by looking at the effects they have on things we can see.

So, what's the closest one to us? This video shows a viable candidate, closer than all known so far.
