Original Caption Released with Image:
Dione and Rhea pair up for an occultation, or mutual event, as seen by Cassini. While the lit portion of each moon is but a crescent, the dark side of Dione has begun to take a bite out of its distant sibling moon.

Dione is 1,126 kilometers (700 miles) across and Rhea is 1,528 kilometers (949 miles) across.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 17, 2006 at a distance of approximately 3.4 million kilometers (2.1 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 120 degrees. Resolution in the original image was 21 kilometers (12 miles) per pixel on Dione and 25 kilometers (16 miles) per pixel on Rhea. The image has been magnified by a factor of two and contrast-enhanced 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 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.

Explanation: Arriving at Saturn in July of 2004, the Cassini spacecraft has now spent a year and a half exploring the magnificent rings and moons of the distant gas giant. The year 2005 began with Cassini’s Huygens probe landing on Saturn’s large moon Titan. Cassini’s continuing series of close flybys also revealed details and discoveries across the surface of the smog shrouded moon. In fact, with a ringside seat throughout 2005, Cassini’s cameras have made spectacular pictures of Titan along with Saturn’s other moons and rings almost common place. But often, Saturn itself provided the most dramatic backdrop. In this view, Saturn’s moon Dione lies in front of edge-on rings and the gas giant’s cloud tops draped with broad ring shadows. Dione is 1,118 kilometers across and lies about 300,000 kilometers from the ring’s edge.

Ringside With Dione November 9, 2005

Saturn's moon Dione in the foreground is enriched by gold and blue hues of planet’s rings in the background.

Cassini’s view of Saturn’s icy moon Dione is enriched by the tranquil gold and blue hues of Saturn’s rings in the background. The thin, curving shadows of the C ring and part of the B ring adorn the northern latitudes visible here, a reminder of the rings’ grandeur.

It is notable that Dione, like most of the other icy Saturnian satellites, looks no different in natural color than in monochrome images. Images taken on Oct. 11, 2005, with blue, green and infrared (centered at 752 nanometers) spectral filters were used to create this color view, which approximates the scene as it would appear to the human eye.
