  Cassini looks toward the dark side of Saturn's largest moon as an incomplete circle of light is produced by sunlight scattering through the periphery of Titan's atmosphere.

A detached, high-altitude global haze layer encircles Titan (5150 kilometers, 3200 miles across). See PIA07774 to learn more. North on Titan (5150 kilometers, 3200 miles across) is up and rotated 10 degrees to the right.

The image was taken with the Cassini spacecraft narrow-angle camera on March 16, 2010 using a spectral filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The view was obtained at a distance of approximately 1.9 million kilometers (1.2 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 158 degrees. Image scale is 11 kilometers (7 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.
