On the next episode of Star Talk, it's a cosmic queries edition with of course Chuck Nice.

And we have as our guest David Grinspoon, a friend and colleague, his expertise is on exoplanets,

the search for life, and astrobiology.

And we have some great questions coming up for you.

Like, is carbon-based life the only kind of life that can exist?

Is it the only kind of life we're searching for?

Might we be missing something?

And if we do find life, is there a protocol?

Also, what would an Earth-like planet that sustained life be like if it had no atmosphere?

And will Earth ever become Venus?

With a runaway greenhouse that's nearly a thousand degrees Fahrenheit on this next episode of Star Talk.

Star Talk begins right now.

David, welcome back to Star Talk.

Hey guys, thank you. It's great to be here. Great to see you both.
