Photo: Saturn Lightning Storm Breaks Solar System Record



Saturn's moon Tethys (the small circle pictured above) is seen near storms raging on Saturn's southern hemisphere (shown as white swirls) in a 2008 Cassini image.

The tempest—which has gripped the ringed planet since mid-January—is the longest-lasting lightning storm ever detected in our solar system, astronomers announced in September 2009.
