  Cassini looks down toward Janus, which hugs the outer edges of Saturn's rings.

Janus (179 kilometers, 111 miles across) orbits Saturn about 11,250 kilometers (6,990 miles) beyond the narrow core of the F ring.

This view looks toward the unilluminated side of the rings from about 6 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 26, 2007. The view was acquired at a distance of approximately 2.2 million kilometers (1.4 million miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 31 degrees. Image scale is 13 kilometers (8 miles) per pixel.

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.
