The news from Saturn, this week on planetary Radio. Radio. Hi everyone, welcome to Public Radio's travel show that takes you to the final

frontier.

I'm at Kaplan of the Planetary Society back from our adventure with Planetary Radio

live last week.

We're also back to our regular format and we have another great show for you. Linda Spilker is no longer the deputy project scientist for the Cassini mission at Saturn.

No, she's now the project scientist, but she'll still share the latest science from that magnificent

planet, its mysterious moons, and its beautiful rings.

Did you hear Stephen Hawking's warning about talking to aliens?

Bill Nye has a courageous response in his commentary,

and Bruce Betts will help me give away a copy of the Erie Silence. That's the terrific book

about the search for extraterrestrial intelligence by Paul Davies, the

one I raved about a couple of weeks ago.

Bruce will also provide helpful hints for hopeful beholders of the night sky.

We'll start with Emily Lachtoala, key author of the Planetary Society blog.

Emily, lots of great blog entries over the last week, but a couple that we're going to pay special attention to today

beginning with something that I just found fascinating and I know we've heard from

lots of listeners and you've heard from lots of blog readers about the hexagon on Saturn.

There's one right now who's excited about the hexagon.

Yeah, a lot of readers have asked me about the hexagon on Saturn.

People are mystified by it and of course there's an awful lot of people out there

on the internet who think that a geometrical shape must have an unnatural origin but I can assure you

that it's a very natural in origin the fact that there's six sides to it is actually an accident. It could just as well have been five or seven.
