Repainted Rose, Worlds Colliding, and White Dwarfs of Unusual Size Oct 22, 2026

Show notes

This week we look at the weird results in space science. From looking at how wildly different images from different IR telescopes can be colorized, to worlds colliding, to white dwarfs of unusual size ,and even to Earth's crust on the move, the news was surprising and sometimes a tad bit horrifying. And we present all of it here.

Cloudy with a Chance of Brown Dwarfs: Terrestrial, Exo & Space Weather Sep 24, 2026

Show notes

This week we're doing a weather check.

No Good, Very Bad News and Some Planetary Palate Cleansers Sep 17, 2026

Show notes

Join us as we bounce between the geology behind the recent landslide in Nepal and Tibet, the joy of Saturn's south pole forming a decagon, the frustration of both US and Russian space programs having launch capacity issues, and the good news of BepiColombo getting ready to enter Mercury's orbit.

On Background: The Anatomy of a Comet Sep 01, 2026

Show notes

In this special episode, funded by the National Science Foundation, we're taking a break from the headlines to study the changing anatomy of a comet.

After Hours: Making Moons and Getting Cratered with William K Hartmann Aug 13, 2026

Show notes

Across a long career, Dr William Hartmann has done everything from innovating how the Moon was formed to founding the Planetary Science Institute to defining space art for a new generation; a generation that included host Pamela Gay. Tune in to hear about science, art, and how they can mix as individuals both make new discoveries, and the illustrations to accompany them!

After Hours: Doing Big Science with Light Tools with guest Dr Danny Jacobs Jul 30, 2026

Show notes

Science comes from many corners, and there is a need for both 600-m radio telescopes made on a great plain (Like the RATAN-600) and 60cm radio dishes built in a living room. In this After Hours, we talk with ASU professor Danny Jacobs about how he engages students of all kinds in space sciences through educational tools like the cardboard radio telescope (https://astrochart.github.io), and in space telescope operations with the SPARCS small sat (https://sparcs.asu.edu/)

After Hours: International Moon Day 2026 with guest Jekan Thanga Jul 23, 2026

Show notes

On July 20, the world celebrates International Moon Day. This UN designated holiday marks the anniversary of humanity's first landing on the Moon. The Apollo 11 landing in 1969 is now only a distant memory or a date from history for most people, but it is worth thinking about as the world prepares to return humans to the Moon in the coming decade. Joining us to discuss International Moon Day is Dr. Jekan Thanga, the head of the Space TREx Laboratory at the University of Arizona. Come learn how his interdiciplinary team is taking a page from the past as we plan for a Lunar future.

After Hours: Space Rocks Collected for Science with guest Dr Rhonda Stroud Jul 16, 2026

Show notes

Our solar system readily provides us with free samples of other worlds in the form of meteorites. The trick comes in first recognizing them, and then in understanding what science is locked in their minerals. One major center for collecting and studying these space rocks is Arizona State University's Buseck Center for Meteorite Studies which houses the Carleton B Moore Meteorite Collection. Join us as we discuss the collection with Director Rhonda Stroud.

After Hours: Exploring Physics Through Spaceflight Missions with author Trisha Muro Jul 09, 2026

Show notes

The physics behind modern spaceflight explores everything from aerodynamics to thermodynamics with a lot of kinematics playing a role along the way. We welcome on guest Trisha Muro to discuss her new book, "It's (Just) Rocket Science", which explores how we can learn physics through spaceflight missions.
