Saturn in Color
Explanation: Explanation : Saturn is unusual but photogenic. The second largest planet in our Solar System , behind Jupiter , has been easily identifiable at night since history has been recorded. It was only with the invention of the telescope , however, that any evidence of its majestic ring system became apparent . Saturn itself is composed of mostly hydrogen and helium gas. Saturn's rings are composed of many ice chunks ranging in size from a penny to car. The above picture of Saturn is one of the earliest taken by the Hubble Space Telescope and is a digital reconstruction of three color images. The Cassini mission to Saturn is scheduled to be launched later this year and should reach Saturn in 2004.
