Saturn
Saturn and its spectacular rings, in a natural-color composite of 126 images taken by the Cassini spacecraft on October 6, 2004. The view is directed toward Saturn's southern hemisphere, which is tipped toward the Sun. Shadows cast by the rings are visible against the bluish northern hemisphere, while the planet's shadow is projected on the rings to the left.
Saturn does not have a solid surface. Unlike terrestrial planets such as Earth, Saturn is a gas giant that lacks a distinct boundary between its atmosphere and its interior.1
Instead of a solid crust, the planet consists of layers that transition from gas to liquid as depth and pressure increase. The visible outer layer is a complex of cloud decks, beneath which the atmosphere extends tens of thousands of kilometers, becoming steadily denser and warmer. Deep within the planet, hydrogen exists in a fluid metallic state due to extreme pressures. While scientists believe Saturn likely contains a dense central core composed of a mixture of rock and ice, this region is buried deep beneath the planet's massive gaseous and liquid envelope.12
