Astronomy Cast Episode 261 from Monday, April 16, 2012, lasers and lasers in astronomy.

Welcome to Astronomy Cast, our weekly facts-based journey through the cosmos.

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 University and with me is Dr. Pamela Gay at Professor at Southern Illinois University.

Hi Pamela, how are you doing?

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

Doing really well and I think once again I want just to remind people that if you want a really cool way that you can enjoy astronomy cast wherever you are in any way to check out our Astronomy Cast app in the iTunes store.

It's a $1.99 and then gives you a direct feed to every episode of Astronomy Cast on demand.

You don't have to have them filling up your local drive, you can just play them stream them directly from our server in whatever episode you want.

You can go back, listen to the old episodes, the new episodes, or like my children, you can just leave it on from the time they go to bed and it just keeps running all the way through till morning, burning our batteries.

And Kudos to Fraser, so I have to give him a shout out because he went through and he cleaned up all the content.

So it's much improved if you've looked at it before and gone, yeah, it's fixed now because of Fraser.

Yeah, I went through and did all the titles and then I could see people kept saying like, you guys got to fix the titles in the old shows and I kept,

and finally I downloaded and looked at them like, oh, I see what people are driving.

Yeah, I see the problem here and so then I went through and fixed them all.

And now, you know, we're trying to improve it even some more and try and put in more cool stuff into it.

So anyway, if you've got an iPhone, sorry, Android people, I guess we'll talk about that.

Not there yet.

But if you've got an iPhone, then $99, it's the best thing you'll ever buy ever.

Maybe.
