Episode 17 --- How We All Got Here --- Galaxy Evolution over Cosmic Time

For anyone who’s ever wondered how our own star happened to be caught up in the midst of a grand spiral beauty like our Milky Way, this episode should at least provide some clues.  It’s a big cosmological subject and of course, we just skim the surface but for those curious as to how galaxies formed after the Big Bang to become home to oh so many stars, this podcast episode should be of interest.  This week’s guest, Francesca Rizzo, a doctoral candidate at Germany’s Max Planck Institute for Astrophysics in Garching, discusses the current state of how galaxies formed and developed over cosmic time.
