It’s time for school! The Astro101 series will cover some of the most important questions in astronomy. In today’s lesson, we’ll have: What are the different kinds of stars? Why does classification in astronomy make no sense? How the heck do we define a “star”, anyway? I discuss these questions and more in today’s Ask a Spaceman!
