The Aurora and the Sunrise

Auroras and the Magnetosphere of Jupiter
6.04.2016
Jupiter has auroras. Like near the Earth, the magnetic field of our Solar System's largest planet compresses when impacted by a gust of charged particles from the Sun. This magnetic compression funnels charged particles towards Jupiter's poles and down into the atmosphere.
