Cassini spots the irregularly shaped icy moon Janus as it swings around Saturn.
This view looks toward the unilluminated side of the rings from about 8 degrees above the ringplane. Janus is 179 kilometers (111 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 19, 2008. The view was obtained at a distance of approximately 1.6 million kilometers (994,000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 18 degrees. Image scale is 10 kilometers (6 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.
