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 is a galaxy? What does our own galaxy look like? What are the different kinds of galaxies, and how did they get that way? I discuss these questions and more in today’s Ask a Spaceman!
