Show Notes
Jim Cooney joins Josh and Addie to talk about the origin of galaxies and the observation of a galaxy from when the universe was but a teeny weeny baby of a universe, less than 1/12th its current size. Also, Scott Kelly is back on terra firma and has to deal with gravity. Hear all about redshifts, the big bang, and hyposprays on this episode of Walkabout the Galaxy.
