APOD 1.6- Auroras of Saturn

In order to investigate why auroras occur on Saturn scientists have looked at many infared photos of the planet previously taken by the Cassini spacecraft. Auroras can occur and are effected depending on Saturn's rotation and the angle of the Sun. Saturn's moon can also effect the auroras taking place in the magnetosphere, which like Earth's, deflects the solar wind particles being emitted by the Sun. The angle of the solar wind particles coming from the sun and the rotaion of Saturn will tell where the particles will be deflected on Saturn's surface. However, Saturn's auroras can occur over an entire pole, as opposed to merely the magnetic poles, where they happen on Jupiter and Earth. Saturn reflects a glowing red, while its ring appear to be a very bright blue as they reflect the most light from the Sun.
