Cassini delivers this stunning vista showing small, battered Epimetheus and smog-enshrouded Titan, with Saturn's A and F rings stretching across the scene.
The prominent dark region visible in the A ring is the Encke gap (325 kilometers, 200 miles wide), in which the moon Pan (28 kilometers, 17 miles across) and several narrow ringlets reside. Moon-driven features which score the A ring can easily be seen to the left and right of the Encke gap.
In an optical illusion, the narrow F ring, outside the A ring, appears to dim across the disk of Titan. A couple of bright clumps can be seen in the F ring.
Epimetheus is 113 kilometers (70 miles) across and giant Titan is 5,150 kilometers (3,200 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2006, at a distance of approximately 667,000 kilometers (415,000 miles) from Epimetheus and 1.8 million kilometers (1.1 million miles) from Titan. The image captures the illuminated side of the rings. The image scale is 4 kilometers (2 miles) per pixel on Epimetheus and 11 kilometers (7 miles) per pixel on Titan.
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.
