Just like on Earth, the planet Saturn also has auroras, as seen in this Hubble Space Telescope image.

Hubble's unique ultraviolet image of Saturn's auroras helped to show that these storms are caused mainly by the pressure of the solar wind, a stream of charged particles from the Sun. The bright auroral display in this image, taken in January 2004, corresponds to the arrival of a large disturbance in the solar wind.

While Earth's auroras usually last for minutes or hours, Saturn's can last for days!
