Astronomy Cast Episode 375, the search for life in the solar system.

Welcome to Astronomy Cast, our weekly facts based journey through the cosmos, where we help you understand not only what we know, but how we know what we know.

My name is Fraser Kane, I'm the publisher of Universe today, and with me is Morgan Ranberg, a graduate student in the Department of Astrophysical and Planetary Sciences at the University of Colorado at Boulder.

Hey Morgan, how you doing?

Hey Fraser, it's good to be back.

Good to be back here. We do this, we seem to do this every year. So it's been around a year since you joined me on Astronomy Cast and we did a very special episode of Astronomy Cast about Saturn's rings.

This time around we are going to be doing a different show, still about ice and water, about the search for life in the solar system or the search for water in the solar system.

And then there for life. So, but we are doing this episode as part of the Cosmic West 2015 Hangout of Phon.

So if you're listening to this show, we are still taking donations for the Hangout of Phon, but it's still going to be doing it for weeks and months after the show itself.

So even though it's probably been a couple of weeks since the Hangout of Phon's happened, you can still participate. So just go to CosmicWest.org, slash Hangout of Phon, and you can give some donations to help us keep all of the educational and outreach activity that we do on the air. We really appreciate it.

With the discovery of water ice in so many locations in the solar system, scientists are hopeful in the search for life on other worlds.

So Morgan Redberg returns to Astronomy Cast to explain the best places we should be looking for life.

Alright Morgan, so your day job, graduate student, what do you do?

Yeah, so I study the rings of Saturn as part of NASA's Cassini mission.

Cassini's now been in orbit about Saturn for going on 11 years.

It's hard to believe that we've been studying Saturn that long, but every time we look at something, we discover something new.
