From 2010 to 2011, a storm raged on Saturn. Over time, the storm has been stretched into the white band seen in the mid northern (upper) latitudes. This view, taken on March 12, 2011, shows the late stages of the storm.
It was taken using the Wide Field Camera 3 (WFC3) camera on the Hubble Space Telescope, with color data taken from earlier images of a previous storm by its predecessor, the Wide Field Planetary Camera 2 (WFPC2).
Three moons are visible above Saturn's rings: from left to right, they are Dione, Enceladus, and Tethys. (space.jpl.nasa.gov)
