Description
Deutsch: Video von Saturn und seinen Polarlichtern in ultraviolettem Licht von 115 und 125 Nanometern Wellenlänge von senkrecht über dem Äquator, aufgenommen 2009 vom Weltraumteleskop Hubble
English: Image of Saturn and its polar aurorae from vertically above its equator in light of 115 and 125 nanometres of wavelength (ultraviolet light) taken by the Hubble Space Telescope in 2009.

In January and March 2009, astronomers using NASA's Hubble Space Telescope took advantage of a rare opportunity to record Saturn when its rings were edge-on, resulting in a unique movie featuring the nearly symmetrical light show at both of the giant planet's poles. It takes Saturn almost thirty years to orbit the Sun, with the opportunity to image both of its poles occurring only twice during that time.

The light shows, called aurorae, are produced when electrically charged particles race along the planet's magnetic field and into the upper atmosphere where they excite atmospheric gases, causing them to glow. Saturn's aurorae resemble the same phenomena that take place at the Earth's poles.
