We're inferring that there is a liquid water reservoir under the surface and it's erupting in a geyser-like fashion, maybe like the Yellowstone geysers you would see.
I don't think Saturn's rings will disappear anytime soon, but this tells us how the rings are evolving and how long they might last.
If it had formed anywhere other than around Saturn, it would be a planet in its own right.
I suspect there are more moons there than we know off.
I think it surprised me in just how Earthlike Titan's surface appeared to be.
We're trying to understand how the rings are evolving. To me, that will be the most exciting time.
We call this 'Cold Faithful'. The moon is one thousandth as big as our moon and has one, one-hundredths of Earth's gravity.
We think the core is made of liquid hydrogen and helium.
This could be one of the biggest discoveries of the decade.
In a sense Saturn is almost like a miniature solar system.
