Saturn Storm Postcard

Saturn Storm Saturn Storm ... the huge storm churning through the atmosphere in Saturn's northern hemisphere overtakes itself as it encircles the planet in this true-colour view from the Cassini spacecraft. This picture, captured on Feb. 25, 2011, was taken about 12 weeks after the storm began, and the clouds by this time had formed a tail that wrapped around the planet. Some of the clouds moved south and got caught up in a current that flows to the east (to the right) relative to the storm head. This tail, which appears as slightly blue clouds south and west (left) of the storm head, can be seen encountering the storm head in this view. This storm is the largest, most intense storm observed on Saturn by the Voyager or Cassini spacecraft.
