CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Dark Side Ring of Light
[For trouble viewing the images/movies on this page, go here]
Cassini looks toward the dark side of Saturn's largest moon as a circle of light is produced by sunlight scattering through the periphery of Titan's atmosphere.

A detached, high-altitude global haze layer encircles the moon. See PIA07774 to learn more. North on Titan (5150 kilometers, 3200 miles across) is up and rotated 2 degrees to the left.

The image was taken in visible blue light with the Cassini spacecraft narrow-angle camera on Oct. 9, 2009. The view was acquired at a distance of approximately 1.4 million kilometers (870,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 157 degrees. Image scale is 9 kilometers (5 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.
