A line of dark vortices charge through Saturn's "Storm Alley" -- a region that has seen intensive storm activity since Cassini began its observations of the planet in early 2004.
The image was taken with the Cassini spacecraft wide-angle camera on May 19, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 728 nanometers. The view was obtained at a distance of approximately 863,000 kilometers (536,000 miles) from Saturn. Image scale is 48 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.
