The Cassini spacecraft has spotted an 8000-kilometer-wide, hurricane-like storm around Saturn's South Pole, NASA announced on 9 November. The storm has a dark 'eye' at the South Pole along with eye-wall clouds and spiral arms, but it is not known if moist convection-the driver of hurricanes on Earth-drives the Saturn storm. A movie taken by Cassini's camera indicates that the winds are blowing clockwise at about 560 kilometers per hour. Although large storms have been observed on other planets in the past-most notably, Jupiter's Great Red Spot-this is the first storm found to have eye-wall clouds and a relatively calm center. Andrew Ingersoll, a member of Cassini's imaging team at the California Institute of Technology, Pasadena, said the storm looks like a hurricane but is not behaving like one. "Whatever it is, we are going to focus on the eye of this storm and find out why it is there."
