Million-Ring Circus
1. RINGS FROM AFAR
Measuring 175,000 miles wide but as little as 30 feet thick, Saturn’s rings contain debris of varying ages and composition, all revolving at different speeds.
2. THREE MOONS
Titan and Dione, along with speck-sized Prometheus appear in rare alignment. Tiny so-called shepherd moons help shape the rings and prevent them from dispersing.
3. TITAN
Concentric rings wind in front of Satrun’s biggest moon, Titan, with tiny Janus in teh foreground. The rings are so massive that they have their own atmosphere, separate from Saturn’s. Cassini found evidence of oxygen all around the icy rings.
4. RINGS CLOSE UP
