Coming up next on Stark Talk, our go-to Cosmo chemist Natalie Starky from the UK returns.

And we talk about NASA's Osiris Rex sample return mission from the Earth Crossing asteroid

Benu. Well, we learned how did we accomplish this feat? What do we hope to find?

And we'll asteroid Benu ultimately hit Earth in the year 2182.

All that and more on Stark Talk.

Welcome to Stark Talk. You're a place in the universe where science and pop culture collide.

Stark Talk begins right now.

This is Stark Talk. You'll digress Tyson here. You're a personal astrophysicist.

We're doing cosmic queries. Cosmic queries today. And you know I can't do that without

Chuck Knies. Chuck, how you doing, man? Hey, Neil, what's happening, buddy?

Yeah, yeah. Guess who we have as a guest today. I'll play along even though I can see

her on the screen right now. Who could that be? Who could that be? She is our resident

Cosmo chemist. Yes. How many people get to say that? Nobody gets. We get to say that.

No, yeah. Not even a people who work at Cosmo get to say that they're a Cosmo chemist.

Yes. Yes. Natalie Starkey. Thanks for coming back to Stark Talk.

No, no problem. I love to be here. I want to chat. I want to chat. Cosmo chemistry.

Oh my gosh. That's your professional expertise. And you know, people don't think that the universe

involves other fields, right? I used to start out as a geologist. And of course there's geology

on rocky planets. And then you want to know what the chemistry is. We got to tap people who've

got these kind of expertise. And you're just that kind of person that plugs one field into another

or cross-polytes. Well, I never realized to myself. You know, when I start out, I just liked

rocks, I liked volcanoes. And then slowly you start to learn more. And then you realize, of course,
