Walkabout the Galaxy

It may sound like the title of an astroquark's sex tape, but we actually do have news about a potentially new long-term resident of the solar system captured from another planetary system, and Top astroquark Jim Cooney tells us all about a black hole gobbling up so much stuff that it's the brightest object in the universe! Honorary "Bottom" astroquark Dr. Zoe Landsman joins us to discuss these odd objects, Deadpool and Solo, and asteroid trivia.

We all know Mars is crunchy on the outside, but does it have a chewy center? The NASA Mars InSight mission is en route to the red planet to answer that question. The astroquarks talk about InSight's science and instruments, Han Solo, and Richard Feynman in another wide-ranging episode of Walkabout the Galaxy!
