Episode 10: Stellar Evolution

Ten episodes is a personal milestone! To celebrate, I'm talking about one of my favorite subjects in astronomy--stellar evolution. How are stars born? What happens when they die? What's a rock n' roll star?

Come with me and take a ride on--and off--the main sequence!
