Nasa / Reuters The Cassini spacecraft took this mosaic of the planet Saturn and its rings backlit against the Sun on October 17, 2012 using infrared, red and violet spectral filters that were combined to create an enhanced-color view, in this handout image courtesy of NASA. The images were obtained with the Cassini spacecraft wide-angle camera at a distance of approximately 500,000 miles (800,000 kilometers) from Saturn. Also captured are two of Saturn's moons: Enceladus and Tethys. Both appear on the left side of the planet, below the rings. Enceladus is closer to the rings; Tethys is below and to the left.
