A Look at the Inside of Saturn

The Giant planets do not have the same kind of layers inside that the earth-like planets do. The history of the giant planets was so different that they formed with much more gas on the inside.

Saturn is made of the simple molecules hydrogen and helium, and they become liquid in the environment that is found deep inside Saturn.

Motions inside Saturn help form the powerful magnetosphere of Saturn. Heat from within Saturn contributes to the unusual movements of the atmosphere.
