  This colorful view, taken from edge-on with the ringplane, contains four of Saturn's attendant moons.

Tethys (1,062 kilometers, 660 miles across) is seen against the black sky to the left of the gas giant's limb. Brilliant Enceladus (504 kilometers, 313 miles across) sits against the planet near right. Irregular Hyperion (270 kilometers, 168 miles across) is at the bottom of the image, near left.

Much smaller Epimetheus (113 kilometers, 70 miles across) is a speck below the rings directly between Tethys and Enceladus. It casts an equally tiny shadow onto the blue northern hemisphere, just above the thin shadow of the F ring.

Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft wide-angle camera on July 24, 2007 at a distance of approximately 2 million kilometers (1.2 million miles) from Saturn. Image scale is 116 kilometers (72 miles) per pixel on Saturn.

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.

Fantastic image, as usual. Epimetheus, by the way, is HARD to find; I've found just its shadow.
