Saturn is the crown jewel of the solar system, beautiful and fascinating. It is a gas giant, and has a broad set of rings made of ice particles. Moons create gaps in the rings via their gravity. Saturn has dozens of moons, including Titan, which is as big as Mercury and has a thick atmosphere and lakes of methane; and Enceladus which has an undersurface ocean and eruptions of water geysers. While we are still uncertain, it is entirely possible that either or both moons may support life.

Those Kerbal Space Program figurines though…

The Jolly Pidgeotto says:

isnt enceladus responsible for some of the debris in the F ring as well?

Christine Goni says:

i like saturn rings but not just that

I laughed when Thought Cafe made 5 year old Phil bald.

Robert Billing says:

A few years back I was on vacation in Florida. It was a warm evening and Saturn was up. Lots of people were drifting in and out of the beach bar. I clamped a pair of binoculars onto my camera tripod, aimed at Saturn, and we all took turns having a look. One of the best evenings of my life.

Aba Zaba says:

so much CGI… Why dont you show a real photo? None of these "pictures of saturn" look alike.. i call B.S.

Shawn MMiller says:

Belle Pate says:

I can't wait to see Saturn! This show is truly inspiring! The host is so passionate about astronomy he makes it all sound so poetic and fascinating (It is of course, but I never had a teacher like him.)

I've seen saturn through a telescope once when i was about 15 years old at a boy scout camp. I just recently got into astronomy and I can't wait to get my own telescope and looking at Saturn once again.

Astronomy IS fun!!!

If you play this in 0.5 speed, he sounds stoned and like he's just coming up with these theories. The best is 00:58 xD
