Stormy Skies
Featured on August 31, 2011
A giant storm rages in the northern hemisphere of Saturn in these two images from the Cassini spacecraft. The image at left shows the entire planet, with the rings forming a thin horizontal line across the middle. The storm is the billowing white feature at top center. It circles all the way around the giant planet. The image at right is a false-color close-up of a small part of the storm. Blue clouds are the highest, with yellow or white below them, then red and brown, and finally deep blue. The storm clouds probably are made of water ice covered by crystallized ammonia.
