Several Kepler Planets Turn Out to be Small Stars Mar 16, 2022

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.

Earthquakes Can Affect Plate Tectonics in a Feedback Loop Mar 15, 2022

Researchers studying GPS data collected from the 1999 İzmit earthquake in Turkey found that the quake changed the movement of the plate, and this effect may be possible for other tectonic plates. Plus, more pretty images, starspots merging, melting Arctic sea ice, and minerals on Mars.

Magnetic Fields Help Find Ocean Worlds Mar 11, 2022

Researchers have determined how to effectively measure the magnetic fields at Neptune to determine if any of the moons are ocean worlds… in just twelve minutes. Plus, lasers recreate galaxy cluster conditions, some mind-bending new math, how the Earth’s crust developed, and a look at the long history of Daylight Saving Time.

Science of the Weird: Black Holes, Astronaut Blood, and Alligators Mar 10, 2022

Today’s science stories run the gamut of the strange and the weird, with several black holes, the effects of space on astronaut blood cells, and how alligator mating dances added to solar science. Plus, this week’s What’s Up helps you choose binoculars for sky gazing.

Happy 20th Birthday to Hubble’s ACS Instrument Mar 09, 2022

The Advanced Camera for Surveys instrument onboard the Hubble Space Telescope is celebrating twenty years of service this week. Plus, a new look at an old lunar rock, gas rings around an aging star, all the rockets from around the world, and this week in rocket history, we look back at the 1962 Orbiting Solar Observatory, led by Nancy Grace Roman.

Special Edition: Space Science and the Russia-Ukraine War Mar 05, 2022

Today we’re going to discuss the repercussions to space science of Russia’s invasion of Ukraine. Some people may find this subject upsetting, and if you need to skip this episode, we understand. We’re going to take a look at Roscosmos and how space corporations and nations are imposing sanctions that impact how, when, and what we send to space.

Climate Change - Tsunami, Arctic Sea Ice, and Rising Temperatures Mar 03, 2022

In the latest climate change news, ancient underwater landslides could help us understand tsunami risks in the Middle East, NASA now has a ‘Vanilla’ ice drone to study the Arctic, and lake temperatures are rising. Plus, we bring you joy with this week’s What’s Up and a review of Starlight Cok

Pretty Pictures, Strange Exoplanets, and a New GOES Satellite Mar 03, 2022

To bring some joy into a fraught world, we have rounded up a few of the latest image releases of star mergers and galaxies to brighten your day. Plus, we’ll look at a few strange exoplanetary systems and their amazing science, talk about the latest GOES satellite to launch, and this week in rocket history is all about Envisat.

Black Holes, Fast Radio Bursts, Dinosaurs and Rockets Mar 02, 2022

As we return from our mini-break, we bring you some highlights of stories that happened while we were away, including black holes spiraling toward each other, the possible origin of a fast radio burst, and more information on the demise of the dinosaurs. Plus, Erik Madaus brings us updates on quite a few rocket launches.

Lasers, Life, and Looking at Cosmonaut Brains Feb 18, 2022

Do you want lasers? I want lasers! And today’s show features lots of lasers. We also have more questions than answers about Mars’ methane, misbehaving stars, and new research on how we would look for the early signs of life on other worlds. Plus, a study on how spaceflight impacts the human brain.

Science is the same, every where, every when Feb 17, 2022

The science that dictates our planet is the exact same physics that affects our entire universe. Trying to understand everything around us is just as simple as taking into account all the forces and factors that interact to make everything we see.

Theory and Observation combine to update galaxies and stars Feb 17, 2022

Today our view on the universe gets itself an update thanks to the combined efforts of theorists and observers. From new understanding of how galaxies can lose their darkmatter, to how white dwarfs can be resurrected into Helium burning stars, we have the weird, the wonderful… and in the case of a new lunar tracking system, we even have a touch of the mundane.

Space Junk Hitting the Moon is not From SpaceX Feb 15, 2022

Observers tracking a piece of space debris that is expected to impact the far side of the Moon early in March have now corrected the origin of the object, which isn’t from SpaceX but is from a Chinese Long March 3B involved in the Chang’e 5TI mission. Plus, asteroid 16 Pysche, craters in Wyoming, more launches, and an interview with Katharine Hesse from the TESS mission.

Old Falcon 9 Stage Reenters Over Mexico Feb 14, 2022

The second stage of a Falcon 9 rocket launched in 2017 re-entered the atmosphere over Mexico, breaking up and creating a show of fiery lights in the sky. Plus, dead stars with possibly living planets, more on moon formation, more launches, more launch failures, and a review of “The Apollo Murders” by Chris Hadfield.
