  The distinctive, wispy system of fractures on the trailing hemisphere of Dione (1,123 kilometers, 698 miles across) shows a great deal of contrast in this ultraviolet view.

North on Dione is up and tilted 30 degrees to the left.

The image was taken with the narrow angle camera on March 7, 2005, using a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The image was acquired from a distance of approximately 1.6 million kilometers (1 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 50 degrees. Resolution in the original image was 9 kilometers (6 miles) per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility.

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.
