This could be one of the biggest discoveries of the decade.

In a sense Saturn is almost like a miniature solar system.

We think the core is made of liquid hydrogen and helium.

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.

We call this 'Cold Faithful'. The moon is one thousandth as big as our moon and has one, one-hundredths of Earth's gravity.

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.
