An irreverent and informative tour of the latest, greatest and most interesting discoveries in astronomy.

Walkabout the Galaxy got its start from our coffee break "walkabouts" at the University of Central Florida. Josh is not a coffee drinker, so instead of a “coffee break” he takes a walkabout the UCF campus with his colleagues. The wide-ranging conversation on these breaks, from the latest astronomy news to the latest developments in science fiction were so much fun that Walkabout the Galaxy was born. This conversational podcast covers the latest news in astronomy and physics at a level accessible to anyone who is interested in space or just wants to join in a fun and occasionally silly conversation.

WtG is hosted by Josh Colwell, Addie Dove, and Jim Cooney. All three are in the Physics Department and the Florida Space Institute at the University of Central Florida. Josh and Addie study dust, rings, comets, moon, asteroids, and planet formation, and they try to drag Jim into their planetary escapades, but his passion is cosmology.
