The dark side of the ringplane glows with scattered light, including the luminous F ring which shines like a rope of brilliant neon. Below, Dione (1,123 kilometers, 698 miles across) presents an exquisitely thin crescent.
The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers. The image was acquired with the Cassini spacecraft narrow-angle camera on May 3, 2006 at a distance of approximately 1.8 million kilometers (1.1 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 160 degrees. Image scale is 11 kilometers (7 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.
