This interesting vortex in Saturn's atmosphere is surrounded by a halo of bright clouds that extend away toward the east and west. Storms like this one seem to be bright at all wavelengths at which Cassini observes them.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 24, 2006, at a distance of approximately 2.9 million kilometers (1.8 million miles) from Saturn. The image scale is 17 kilometers (11 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
