This atmospheric close-up shows a bright, somewhat distorted feature in Saturn's southern hemisphere. This feature might be a transient eddy which formed and then collided with an obstacle (perhaps a vortex) in the zone of wind shear between two opposing east-west flowing jets. It could also simply indicate a place where two jets are interacting.
The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on March 7, 2006, at a distance of approximately 2.9 million kilometers (1.8 million miles) from Saturn. The image scale is 17 kilometers (10 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.
