Episode 47: Gracefully Aging Galaxies

In today’s episode, we learn all about the clues that Kevin has benevolently placed within the Universe to teach us about the graceful and multifaceted field of galaxy evolution. Alex describes how much the galaxies of today can learn from their wise, high-redshift ancestors through Lyman-alpha emission, while Will segues into the mysterious properties of one of the most nearby aged galaxies. Malena shares a snazzy sonification of a hidden neighbor, as well as her school bus seating habits.
