Astronomy Cast Episode 506.

It's not aliens until it's aliens.

Welcome to Astronomy Cast, a weekly facts-based journey through the cosmos, where we help

you understand not only what we know, but how we know what we know.

I'm Frisor Cain, publisher of the universe today with me as always, Dr. Pamela Gay, a

senior scientist for the Planetary Science Institute, and the director of CosmQuest,

a Pamela, how are you doing?

I'm well, how are you?

Good, we're here in the same room, actually interacting, so if it all sounds so much more fluid

and natural, it's because we can actually like talk to each other.

Well, we can always talk to each other, but like we're in the same place and there's

no weird internet noise and stuff and things and dropped bits.

Right.

It's just drop sound waves.

Now, you sometimes warn us that you might have a tornado flowing through.

There we're recording.

There might be fireworks going on at some point in the middle of this episode, but we're

in Alabama for ThinkerCon.

Hopefully we're going to see some of you tomorrow night when we dinner under a rocket.

Which will have been two nights earlier.

Yeah, when you get this, it will have already happened.

That dinner will have already happened.
