What's more fun than talking about astronomy? Having really engaged kids that are as interested in it. I learned a few things, too. Did you know, for example, that there's a black hole at the center of our galaxy? And that our sun is actually a star and when it explodes, it'll create a million -- no, sorry, one million -- baby stars? Also, it's a white dwarf?
Further, when I politely correct an enthusiastic six-year-old that our star isn't actually a white dwarf, that, "well, your opinion is wrong."
Oh well. At least I did my best.
