This stunning Cassini image shows that Saturnís atmosphere is an active and dynamic place, full of storms and powerful winds. This view is of the planetís southern hemisphere and shows dark storms ringed by bright clouds. The line along the limb of the planet is an artifact of the contrast-enhancement used to bring out features in the atmosphere.
The white churning clouds are at a latitude where winds blow to the west Ė one of the few such places on Saturn. This latitude has been active since the beginning of 2004 and has been informally named "Storm Alley" by Cassini imaging scientists.
The image was taken with the narrow angle camera on September 19, 2004, from a distance of 8.3 million kilometers (5.2 million miles) from Saturn through a filter sensitive to wavelengths of infrared light centered at 750 nanometers. The image scale is 49 kilometers (30 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
