  In this unusual view, Cassini captured two icy moons, Tethys (1,062 kilometers, 660 miles across) and Enceladus (504 kilometers, 313 miles across), in a single narrow angle frame. Little detail is visible on the surface of bright Enceladus, but battered Tethys shows many craters and the huge canyon system, Ithaca Chasma.

The image was taken in visible light with the narrow angle camera on January 29, 2005, from a distance of approximately 3.7 million kilometers (2.3 million miles) from Tethys and 3.5 million kilometers (2.2 million miles) from Enceladus. Resolution in the original image was 22 kilometers (14 miles) per pixel on Tethys and 21 kilometers (13 miles) per pixel on Enceladus. 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.
