On our next episode, Dr. Audrey Martin joins us to talk about strange spectra from the Trojan asteroids, we learn about micro-tectonics on Europa, and we take a look at axions - potential dark matter - and how we might see them. Coming on #WalkaboutWednesday

Check out Axions and Trojans, available now on all platforms, to hear about a cool way we may detect axions, funny names that were considered instead of "axion", and the strange infrared spectra of the Trojan asteroids. walkaboutthegalaxy.libsyn.com/trojans-and-ax…

We're back and kicking off 2023 with Top quark back in the quark saddle (is that a thing?) to learn about the nuclear fusion breakthrough, Mars sample return, and weird solar oscillations. Available everywhere.

It's #walkaboutwednesday and we've got a cool story about the Milky Way's disk of satellite galaxies and the formation of super-Earth exoplanets in circumstellar disks. We also have rocket trivia and a cosmological stumper. Available on all podcast platforms now!

There's a kind of hilarious but also interesting update on wormholes, as well as a cool new idea to explain the odd distribution of the sizes of exoplanets. Check it all out and test your telescope trivia on the latest episode of WtG. Available on all platforms now.

Everything is mysterious on our next episode, from the Earth's core, to rings around a centaur and the elusive nature of neutrinos. Coming on #walkaboutwednesday to a podcast distributor near you.

Learn about a ring around a small, distant world that defies what we thought we new about planetary rings, a remarkably simple experiment that teaches us something about how remarkably complicated water is, and cosmological magnetic fields. WtG 310 is walkaboutthegalaxy.libsyn.com/whacky-water-a…

It's still #WalkaboutWednesday new episode out now. It's definitely not about - well you'll have to listen. walkaboutthegalaxy.libsyn.com/runaway-black-…

Find out about the surprising complexities of timekeeping and the surprising extent of the Milky Way galaxy, and much more, on our latest episode, out now. walkaboutthegalaxy.libsyn.com/its-about-time…

Hear about the exciting discovery that appears to demonstrate volcanic activity on Venus only 30 years ago (that’s 30 with no million!). We get off to a bit of a silly start, so jump ahead to 24 minutes if you want to skip straight to the science. walkaboutthegalaxy.libsyn.com/active-volcani…

Learn about a new detection of dark matter near black holes in our galaxy and the explanation for the weird motion of interstellar comet Oumuamua. For our local listeners, come meet the Astroquarks at #MegaCon2023 where we’ll record an episode with an audience Sunday at 11:15 am.

Fun coincidence: our next episode, recorded live at #MEGACONOrlando2023, was sponsored by Mega-Constellations.

We had a great time @MegaconOrlando with Brendan Byrne talking about some of the amazing results from JWST's first year of operations, from distant black holes to not-so-distant planets. walkaboutthegalaxy.libsyn.com/megacon-2023-a…

Top quark returns to tell us about planet-forming ingredients in an unexpected place, while the history of water on Mars gets a new twist that's bad news for life on the red planet. walkaboutthegalaxy.libsyn.com/the-impact-of-…

We had an upload error with episode 318! It’s been fixed now but if you downloaded that episode before Sunday, April 30 at 10:23 AM Eastern daylight time you’ll only get half of the episode. Please reload and sorry for the inconvenience!

Check out our latest episode with strange rings, strange moons, strange black holes, and computer trivia that's too nerdy even for top and down astroquarks. Available at the usual places on this #WalkaboutWednesday walkaboutthegalaxy.libsyn.com/crazy-rings-wa…

Learn about the clever ways scientists are digging into whether the universe has a preferred orientation on our latest episode, available now. walkaboutthegalaxy.libsyn.com/is-the-univers…

Catch our latest episode where we learn about a double-supermassive-black-hole system, a gravitationally lensed supernova, new asteroid missions, and much more. walkaboutthegalaxy.libsyn.com/supernovae-nea…

Our next episode publishes at the moment of the 2023 northern summer solstice. We learn about new results on the formation of the Earth as well as the history of the length of the day and the consequences of supermassive black hole mergers. Check it out on the solstice.

We discuss the discovery of the ultra-low-frequency gravitational waves likely due to the collisions of supermassive black holes and evidence for recent climate change on Mars on our latest episode, available now. walkaboutthegalaxy.libsyn.com/the-rumble-in-…
