  Janus peeks out from beneath the ringplane, partially lit here by reflected light from Saturn. A couple of craters can be seen on the moon's surface. To the right, two faint clumps of material can be seen in the dynamic F ring.

The perspective in this view may be a bit confusing-Cassini is gazing toward Janus (179 kilometers, 111 miles across) from just beneath the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 16, 2006 at a distance of approximately 2.1 million kilometers (1.3 million miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 103 degrees. Image scale is 12 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.
