| 2024-07-18 | In this light episode of Walkabout the Galaxy, Josh and Audrey discuss the first confirmation of open spaces in lava tubes connected to lunar pits on the Moon. 200 lunar pits have been observed on the Moon, and now scientists have used radar data to de... |

| 2024-07-11 | You'll be amazed at how much we can learn from iron meteorites. Who would have guessed that analysis of the compositions of these humble metallic remnants of asteroids would be able to tell us about the shape of the protoplanetary disk? We'll learn abo... |
|
| 2024-06-27 | The clock is ticking on T Coronae Borealis which seems primed to undergo a nova explosion this summer. That will make this otherwise faint star as bright as Polaris thanks to a burst of nuclear fusion reactions on the exposed surface of this white dwar... |
|
| 2024-06-20 | We take a look at some Beta Pic Disk shots before journeying back to the earliest era of the universe and the possible formation of primordial black holes. Some of these may have been only the size of an atom and would have long since evaporated throug... |
|
| 2024-06-12 | The Astroquarks celebrate their 360th episode with discoveries showing carbon much earlier in the universe than previously thought possible, and an exotic new proposal as an alternative to dark matter. Plus, we have radioactive trivia and a slew of spa... |
|
| 2024-06-05 | There is a mountain - or should we say a volcano - of evidence, building that suggests volcanic activity on Venus during the time of the Magellan mission in the 1990s. We’ll dig into that, struggle to get our script right, ponder the Fantastic Voyage, ... |
|
| 2024-05-30 | New observations of Erigone, the parent body of an asteroid family, indicate its rocks are juicy with water. That makes it both a potential resource for future missions but also shows that asteroids may have played a big role in delivering water to the... |
|
| 2024-05-15 | The Astroquarks delve into the possibility of giant alien constructs around stars, and the strange weather on a planet that is unreasonably close to its star. Join us for space news, trivia, and a fun exploration of odd topics in astronomy on Walkabout... |

| 2024-05-08 | NASA's Lucy mission discovered a surprising moon of the small asteroid Dinkinesh on its way to the orbit of Jupiter. New studies of that moon, a contact binary, suggest it may have a surprisingly young age. Meanwhile, cosmologists continue to wrestle w... |
|
| 2024-05-01 | A clever test of dark matter and an alternative theory of gravity to explain the motions of stars around galaxies results in another check in the win column for dark matter. Simulations with the modified model of gravity failed to explain the motions i... |
