Night Side of Titan

Voyager 2 obtained this wide-angle image of the night side of Titan on Aug. 25, 1979 at a high phase angle of 154` and a range of 907,000 kilometers (563,000 miles). Green and violet images were combined to make this photograph. The result is a view of the extended atmosphere of this satellite of Saturn, the bright orangish ring being caused by the atmosphere's scattering of the incident sunlight. The bluish outer ring is further evidence of scattering by the submicron size particles that extend several hundred kilometers above the main clouds. This type of photograph is a direct indication of Titan's extensive atmosphere. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena.
