2010 storm on Saturn (IMAGE) University of California - Berkeley Caption A huge storm dominates the rather featureless surface of Saturn in an image taken by the Cassini spacecraft on Feb. 25, 2011, about 12 weeks after the powerful storm was first detected in the planet's northern hemisphere. The megastorm is seen overtaking itself as it encircles the entire planet. Astronomers have found deep in the atmosphere the aftereffects of megastorms that occurred hundreds of years ago. The dark stripes are the shadows of Saturn's rings.
