A thunderstorm that would encompass an area from San Francisco to the Mississippi River was recorded on Saturn. The storm, recorded by NASA’s Cassini spacecraft, has lasted an amazing 9 months so far and became a record setter for the longest lightning storm recorded in the solar system. The previous longest storm duration was 7 ½ months, also set on Saturn, between November 2007 and July 2008.
Scientists speaking at the European Planetary Science Congress (EPSC) said instruments onboard Cassini recorded the storms that are 10,000 times more powerful than lightning storms on Earth. This record breaking storm is the ninth that the spacecraft has recorded on Saturn since it arrived at the planet in July 2004.
Saturn is well known for its severe thunderstorms that usually occur in an area scientists have dubbed ‘Storm Alley’ – something akin to Tornado Alley in the central United States although much bigger in area and the storms are much more powerful. The area on Saturn lies 35 degrees south of Saturn’s equator and scientists aren’t entirely sure why this area is a hot bed for activity.
