The Generation of Saturn's Magnetosphere

Magnetospheres are generated with 1.) magnetic materials and 2.) with motions within the magnetic material.

The Earth-like planets generate magnetospheres from iron at the center.

But Saturn has almost no iron core. The magnetic material of Saturn is found within the liquid metallic shell. Motions within that shell produce the magnetic field.

The most important motions in the atmosphere are winds. The major winds in Saturn's atmosphere are the zonal winds which are made of zones and belts. Zones and belts blow in opposite directions around...more

Saturn's Belts and Zones

The clouds on Saturn, like Jupiter, are divided into stripes called "belts and zones". In a belt, very powerful winds blow one way. In a zone, very powerful winds blow the other way. These kinds of winds...more
