Saturn's rings are falling into the planet, an Olympic swimming pool of ice every half hour. This is the full history of Saturn: how the second giant formed, why it is lighter than water, how its day was finally timed by ripples in its own rings, how Galileo's "ears" became Huygens' ring, and what Pioneer, Voyager and Cassini found, from methane rain on Titan to an ocean under the ice of Enceladus. Then the big open question: are the rings young, or old and self-cleaning?
