Welcome to Star Talk.

You're a place in the universe where science and pop culture collide.

Star Talk begins right now.

This is Star Talk, Cosmic Queries edition.

And today's subject is Extremophiles and Alien Worlds.

One of my favorite subjects. Chuck, what do you think about that topic?

Kind of sounds like Aliens Gone Wild.

Call right now. It's Aliens Gone Wild.

You've never seen Aliens like this before. It's Extremophiles.

I love me a little bit of this subject.

But we have one of the world's experts on it on Star Talk today.

Kendall Lynch. Kendall, welcome to Star Talk.

Thanks for having me. I'm so excited to be here.

Excellent. Excellent. You have a PhD in this stuff.

But let me just alert people that your expertise is some kind of a malgum of whole field that were previously distinct from one another.

Because I think of geology and I think of biology and I think of modern astrophysics.

And you just took a big fat stapler and crammed them together.

And then you do all three of these all at once. How is that even possible?

It's called astrobiology.

You got to know your geology, too.

It's kind of this interesting thing where you just got to learn to wear a lot of hats.

And you don't necessarily, you should have, ultimately, you have expertise in one thing a little bit more than the other.
