Astronomycast, episode 182 from one day, March 22, 2010, Astronomatory.

Welcome to Astronomycast, our weekly facts based journey through the cosmos, where we help you understand not only what we know, but how we know what we know.

My name is Fraser Cain, I'm the publisher of the University, and with me is Dr. Pamela Gaye at Professor at Southern Illinois University.

Hi Pamela, how are you doing?

I'm doing well, how are you doing Fraser?

Good. Now I got one little piece of news, which is that we've had a couple of radio stations.

Ask if they can run Astronomycast on the air and want our permission and are yes, please.

So if you run a radio station, if you know a radio station and you want to use Astronomycast, feel free, be our guest, free, don't pay ever.

Yeah, totally fine with us, it'd be great if you want to do that.

College radio, NPR, or here in Canada on the CBC, CBC, call me, and you know, ABC in Australia, anything, for free.

Go ahead, play it all you like.

User content for any purpose whatsoever, so just so that's all clear.

But yeah, if you want to email us and wants to do a little promo for you, no problem, that'd be cool.

Alright, let's move on to the show.

So astronomers have been cataloging star positions for thousands of years from the first calculations made by Hipparchus to the more recent star catalogs made by the spacecraft named after them.

This is a stromatory, another way to find our place in the universe.

Alright, Pamela, I guess we need to kind of go right back to the the earliest age.

And I guess at some point, humans realized that there was some kind of rhyme or reason to the position of the stars that they weren't going anywhere.

And that there was, you know, that there's a way to map this.

So I was so, and I think the name that comes to mind is Hipparchus.
