Walkabout the Galaxy

Volcanoes on ancient Earth and not-so-ancient Venus are the main topics for the astroquarks, with planetary trivia, and a giant gassy wave moving through the Milky Way. Catch up on all the different …

The astroquarks explore our origins with from the ancient fossil Lucy to the upcoming asteroid mission of the same name. They then head for the stars, including a nearby one with a potentially habita…

The title has nothing to do with the episode except what could be more fundamental than simply measuring how far away something is? The astroquarks tackle this deceptively complex question on cosmolo…

The astroquarks are wrapped up with the passage of time and the aging of the stars, the universe, and themselves as the first annual year of the astroquark comes to a close. We discuss the red giant …

Walkabout the Galaxy closes out 2019, the first annual Year of the Astroquark, with an episode touching on everything from interstellar comet I2/Borisov to the tiger stripes of Enceladus and the firs…

An asteroid has been observed getting smashed to smithereens by another asteroid! And a medium-sized black hole has been observed, which oddly enough is more interesting than a tiny black hole or a h…

Strange quark is convinced that the swirls on the Moon are actually 2001 monoliths, and all three of your hosts are eager to go check them out. On the way, will the spacetime they're traversing be sm…

An instrument on the International Space Station that can help us understand more about antimatter is getting an upgrade, and we review that old sci-fi staple: the wormhole. Somehow we manage to do t…

Yes, it's just as bad as the title suggests, because when a supermassive black hole in a galactic center really gets going it can shut down star formation in the galaxy by blasting out all the raw st…

Some clever detective work has found one of the smallest black holes known. The astroquarks also take a look at the puzzling mess of the Hubble Constant and the disagreement over its value. Plus, the…

The astroquarks are joined by Dr. Renee Weber from NASA's Mars Insight mission to bring us the skinny on that spacecraft's mole's struggles to burrow into Mars. We also check in on polluted white dwa…

The astroquarks are joined by Dr. Adam Burgasser from the Cool Star Lab at the University of California San Diego to talk about the mysterious members of the astrophysical menagerie that lie between …

The astroquarks spin around the universe, from an ancient tree's rings providing clues to magnetic reversals on Earth to planets wandering among the stars and the first detection of the filamentary s…

The astroquarks welcome Stephanie Jarmak from UCF to discuss the study of gluons, the hilariously named force-carriers that hold quarks together, Trojan asteroids sharing Jupiter's orbit, eyeball pla…

Ever wonder what goes on at an international meeting of planetary scientists? Who hasn't?! This special episode of Walkabout comes to you from a hotel room in Geneva Switzerland following the joint m…

The astroquarks revisit the importance of H2O on the Moon, even if it is tied up inside rocks, before taking a visit to the realm of the Milky Way's gigantic bubbles of plasma emanating, it seems, fr…

Hurricanes are regular visitors to the Walkabout Studios at the University of Central Florida, but not to the planet Venus, whose slow rotation makes for rather dull weather. High of 900 degrees is f…

Join us for a special musical episode of Walkabout the Galaxy with guest Adam LaMee as we take a look at a nearby giant exoplanet and a very distant supernova of a type that has never been seen befor…

Astronomy and cosmology challenge our perceptions of space and time, make us ponder our place in the universe, and give us wonders from the infinitesimal to the nearly-infinite. Then there's Walkabou…

We never get tired of Einstein being right, and once again his general theory of relativity is up to the challenge. The astroquarks take you on a tour to the black hole at the center of the Milky Way…
