The planet Saturn, similar to Earth and Jupiter, has auroral displays at its north and south poles. These auroras -- called the aurora borealis and aurora australis on Earth -- are caused by energized particles from the Sun passing through a planetary magnetic field.
In November 2008, scientists revealed images from the Cassini space probe that show a second, infrared aurora across Saturn's north pole. This aurora, apparently generated by ionized hydrogen, is far larger and covers more area than experimental models predict. The reason for the infrared aurora's unique morphology is unknown.Nature: Complex structure within Saturn's infrared aurora (September 12, 2008)
