Saturn's Mysterious Hurricane Spotted by Cassini Spacecraft
NASA's Cassini spacecraft has provided scientists with the first views of an enormous hurricane swirling around Saturn's north pole. Scientists believe the massive storm has been churning for years. The hurricane's eye is about 1,250 miles wide - 20 times larger than the average hurricane eye on Earth. The thin, bright clouds at the outer edge are traveling over 300 mph, and the hurricane swirls inside a six-sided weather pattern known as the hexagon. Although there is no body of water close to these clouds high in Saturn's atmosphere, learning how these Saturnian storms use water vapor could tell scientists more about how terrestrial hurricanes are generated and sustained.
