Saturn is very similar in composition to Jupiter. Its rings, composed of rock and ice fragments, are more developed than those of other planets (all planets have them), and are just barely visible in a good set of binoculars. (You'll see a 'bulge'). The dark areas are empty orbits where gravitational effects won't allow ring material to remain. Saturn is not very dense; it would float in water. Saturn and its large moon Titan have been visited by the Cassini space probe; find out more about Saturn and Titan.
