Titan
Titan, moon of Saturn, photographed by Voyager 2 on August 25, 1981, at a distance of 907,000 km (564,000 miles). Green and violet images were combined to make this photograph, which shows the extended atmosphere of the satellite.
The lakes found in the polar regions of Titan are filled with liquid hydrocarbons. Observations from the Cassini-Huygens mission confirmed that these features contain liquid rather than ice or sand, as evidenced by reflections of the Sun observed on their surfaces.1
