Saturn's Aurora

This image provided by NASA Nov. 12, 2008 shows the northern polar region of Saturn showing both the aurora and underlying atmosphere, seen at two different wavelengths of infrared light as captured by NASA’s Cassini spacecraft. According to NASA scientists Saturn has its own unique brand of aurora that lights up the polar cap, unlike any other planetary aurora known in our solar system. This odd aurora revealed itself to one of the infrared instruments on NASA's Cassini spacecraft. Auroras are caused by charged particles streaming along the magnetic field lines of a planet into its atmosphere. Particles from the sun cause Earth's auroras. Many, but not all, of the auroras at Jupiter and Saturn are caused by particles trapped within the magnetic environments of those planets.
