Michigan State University-St. Andrews will be hosting their next Virtual Family Astronomy Night from 7 p.m. to 8:30 p.m. on Wednesday, January 12. The theme will be “The Milky Way: our house in space”.
You’ve probably heard that our solar system is part of the Milky Way galaxy. But what exactly is a galaxy? Who coined the name “Milky Way galaxy” in the first place? What do we know about the Milky Way? How big is it, what shape does it have and how many stars does it have? What else is there besides stars in it? How old is he? Are stars still forming? If so, where? Is there a model? Where is the center and how far are we? And if we can’t see the center (which we can’t), how do we know where it is or what might be hiding there?
