The View from Earth
Composed primarily of hydrogen and helium, the upper atmosphere of Saturn exhibits banding similar to that of Jupiter. Unlike Jupiter, however, the individual bands and clouds have little color variations.
The Magnetic Field of Saturn
From Pioneer investigations, scientists discovered that the magnetic field of Saturn is aligned with the planet's axis of rotation, unlike the fields of Jupiter and Earth. This discovery has led to revisions in the theories on the origin of magnetic fields, which had previously relied on an offset between the field's axis and the planet's rotation axis to produce large planetary magnetic fields.
The magnetosphere of Saturn is a large region surrounding the planet where charged particles (protons and electrons) are trapped by the magnetic field. Radiation belts surround Saturn at the orbits of Titan and the larger icy satellites. The source for these particles is most likely the atmosphere of Titan and the surfaces of the icy satellites and ring particles.
