EVSN - JWST Makes Sense of the Early Universe Feb 06, 2026

Show notes

From January 28, 2026.

In this episode we look at highlights from the latest American Astronomical Society Meeting. An accidental theme came out: with each new telescope and each improved instrument we can look more closely at our Universe - we can and do learn more and understand more even about the things we thought we knew best. In this episode, Rubin Observatory brings rapidly rotating asteroids, and JWST peers at objects thriving in the first 2 billion years of our universe. Observatory after observatory brings us new science.

Astronomy Cast Ep. 780: When Asteroids & Comets Attack! Feb 02, 2026

Show notes

https://www.youtube.com/watch?v=sIVunut4Dgk

Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest )

Streamed live on Jan 26, 2026.

We live in a cosmic shooting gallery. It's not a matter of "if" but "when"! Dinosaurs, blah, blah, blah. You know the drill. But seriously, folks, it's raining rocks & ice out there! How seriously should we take it? What happens when a variety of different objects hit the Earth? Different kinds of objects affect Earth very differently when they impact. Let's discuss what makes an impactor more or less dangerous.

Travelers in the Night Eps. 851 & 852: Scientists Views Odds of Aliens & Landing On Mars Feb 01, 2026

Show notes

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 May & June, 2025.

Today's 2 topics:

- In a recent paper published in Nature Astronomy entitled "Surveys of the scientific community on the existence of extraterrestrial life" Dr. Peter Vickers and his team of 10 co-authors report the results of their survey of the lead authors for the past 10 years in the top three astro-biological journals. These researchers sought to measure if their sample group of scientists thought it likely that:

1) simple life, and/or

2) life more complex than terrestrial bacteria, and/or

3) Intelligent life comparable or superior to human beings exists outside of Earth.

For more:

https://cosmoquest.org/x/365daysofastronomy/2014/07/24/july-24th-are-we-alone/

- The good news is a Mars landing by human colonists and their equipment seems technically feasible given a large budget of cash and grit.

Space Stories - Perihelion & Aphelion Jan 31, 2026

Show notes

Hosted by our Director, Avivah Yamani.

Earth swings closest to the Sun at perihelion and farthest at aphelion, words that apply to every planet orbiting the Sun. Learn how Kepler's laws reveal an elliptical orbit, why Earth moves faster at perihelion, and why seasons come from Earth's tilt, not distance.

EVSN - Mystery of Mars' Recurring Slope Lineae Possibly Solved Jan 30, 2026

Show notes

From February 8, 2021.

A new theory has been proposed that could answer the question of what causes recurring landslides on Mars: small-scale ice melting just below the surface may leave the regolith vulnerable to wind. Plus, a look at some of Earth's ancient climate changes, a gamma-ray source, puffy galaxies, and this week's What's Up.
