Seen by the international Cassini mission, Dione’s lit hemisphere faces away from Cassini’s camera, yet the moon’s darkened surface is dimly illuminated in this image by ‘Saturnshine’. Although direct sunlight provides the best illumination for imaging, light reflected off Saturn can do the job as well. Taken on 23 October 2016, at a distance of approx. 504,000 km from Dione.
