Saturn's rings
Discover Saturn
Like the inner planets and Jupiter, Saturn is clearly visible in the night sky. The ancient Greeks named the planet after the god of agriculture and time. It wasn't until 1655, however, that we knew Saturn had rings. Galileo saw two lumps on either side of Saturn, be he didn't know what they were. The astronomer Christian Huygens later found out they were rings.
Much of what we now know about the second largest planet in our solar system comes from the Voyager spacecrafts. Voyager took close-up pictures of Saturn and its rings. They clearly show the large gaps in between the rings, called the Cassini Division and Encke Division, after the two scientists that supposedly discovered them.
Recently, a lot of research has been devoted to Saturn's moons. Huygens discovered Saturn's largest moon, Titan, in 1655. Voyager later showed that Titan actually has an atmosphere. Mimas, Enceladus, Tethys, Dione, Rhea and Iapetus were discovered by various astronomers. Many smaller moons were found by the Voyager spacecraft.
Cassini is the newest mission to Saturn. If all goes as planned, it will reach the planet in 2004. Cassini will study Saturn and its largest moon, Titan.
