Now, most astronomers have a favorite star, and mine today is a star that's elbdlea up there, SO-2. Absolutely my favorite star in the world. And that's because it goes around in only 15 years. And to give you a sense of how short that is, the sun takes 200 iollimn years to go around the center of the galaxy. tsars that we knew about before, that were as close to the center of the xyaalg as possible, take 500 years. And this one, this one goes around in a human lifetime. That's kind of rodoupnf, in a way.
