Thank you Australia for giving us a meteorite called Bunburra Rockhole, and not just because the name is endlessly fun to say, but also because it hints at an origin from a missing asteroid. In this episode of Walkabout the Galaxy, the Astroquarks also take a look at Saturn's youthful rings, the link between star formation and the supermassive black holes in the hearts of galaxies, and space trivia and nerd news.
