Wandering the Cosmos with astronomer Sandra Faber this week on planetary radio.

Welcome, I'm at Kaplan of the Planetary Society with more of the human adventure across our solar system and beyond.

The fireworks may be over in the United States, but they'll continue forever across the farthest reaches of our universe, and maybe

even beyond.

We'll talk for the better part of an hour about galaxies, black holes, the multiverse, and more with the great Sandra Faber, and get her advice

for young scientists.

Then we'll hear what's up in the night sky and offer you a chance to win that new planetary radio t-shirt when Bruce Betts arrives.

First though, we welcome back the CEO of the Planetary Society, Bill Nye, the Science Guy.

Bill, Happy Independence Day holiday. We're recording the day before that big holiday here in the U.S.

Thank you, Matt.

I am a proud U.S. citizen.

I'm a native and the 4th of July means a lot to us.

So does planetary protection, not a very good segue,

but that is what we're going to talk about.

Because you went to an interesting meeting last week.

I think it was interesting.

Well, it was more than interesting, man.

It was, no, it was the meeting of the committee that's part of the National Academies of Science

here in the United States that's establishing, let me see if I can get this correct, the process

by which the protocols will be established.

They're not doing the protocols of protecting Mars

from Earth microbes.
