Astronomycast Episode 253 from Monday, February 20, 2012. Rally, scattering. Or, why is the sky blue?

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 university today, and with me is Dr. Pamela Gay, a professor at Southern Illinois University at Pamela, how are you doing?

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

Yeah, I can hear in your voice your little little under the weather, aren't you?

Yeah, colds happen, and our weather has been bouncing back and forth between high 60s Fahrenheit and 20s Fahrenheit.

And my body said, no, I just said no.

But can we recover enough of your brain this week to answer some basic questions about rally scatter?

I think this week's topic we're going with, are you smarter than a fifth grader?

So I am smarter than a fifth grader, even when drugged.

Okay, good, good.

And so once again, as always, we're recording this episode of Astronomycast as a live Google plus hangout on air.

So if you want to join in on the fun, we record these episodes every Monday at noon Pacific, three Eastern, eight o'clock, Grinch Bean Time.

You can go to CosmoQuest.org slash hangouts, and you'll see more information on the show times, the last episodes that we did, and a viewer that you can watch when we record the show live and a way to participate.

So if you want to, you know, beyond just listen to the episode, but actually participate and join us, because we open it up and people can jump in the hangout and ask us questions about space and astronomy.

So it's a lot of fun. So we highly recommend that you join us if you want.

So go to CosmoQuest.org slash hangouts.
