There are stars, and there are, well, not stars.

And that just about sums up all of the astronomy that we've explored so far in our Astro 101 series.

They're The Story of the Stars and then everything else.

And yes, this is part of a series on getting schooled in basic astronomy.

And it also just about sums up all of astronomy prior to, say, I don't know, like 1900.

There were the things that were stars, and then there was a vast collection of other.

And all the other things seem vastly less important than the stars.

And I know I've been talking a lot in this series about the early

1900s, because it's such a pivotal moment in astronomy. It's where a lot of things

click into place, where astronomy really goes from just measuring positions and recording

things and making spreadsheets to actually explaining what is happening out there in

nature. I see the early 1900s as the advent of astrophysics as we understand it. And since I'm

kind of basically an astrophysicist, it's very near and dear to my heart, this origin of, like,

a lot of modern-day astronomy and astrophysics and cosmology. And in the early 1900s,

you know, a century ago, or I don't know when you're listening to this podcast, it could be

two centuries ago or a millennia ago.

There was so much interest in the stars and how they worked in classifying them. And then there

was just all the other stuff. There were the planets. There were the comets. There were the asteroids.

And there were the nebula.

I've talked about nebula before. And while some nebulae have been known for centuries, like, I don't know, the Andromeda Nebulae.

But some hadn't been known, were just, just back then, getting discovered. I mean, discovered in terms of the European astronomers who are doing this work of astrophysics of trying to explain

what is going on up there. Obviously, there were a bunch of Nebulae that have been known to
