The Colors of Tethys
The Cassini spacecraft has been orbiting Saturn since 2004. Over the last few years, Tethys’ northern hemisphere has been experiencing its summer, allowing the sun to illuminate formerly dark areas of the moon’s surface.
This image was constructed from 52 Cassini images obtained on April 11, 2015 with the Cassini spacecraft narrow-angle camera. The images were obtained at a distance of approximately 33,000 miles (53,000 kilometers) from Tethys. NASA used clear, green, infrared and ultraviolet spectral filters to enhance the colors to make them visible to the human eye.
