Saturn's moon Mimas
Looking like the 'Death Star' from the Star Wars films, this is Mimas, a heavily cratered moon of Saturn, captured here by the NASA/ESA/ASI Cassini-Huygens spacecraft.
Soon after Saturn orbit insertion, Cassini-Huygens returned its best look yet at Mimas (398 kilometres across). The enormous crater at the top of this image, named Herschel, is about 130 kilometres wide and 10 kilometres deep.
The image was taken by the Cassini-Huygens spacecraft narrow-angle camera on 3 July 2004, from a distance of 1.7 million kilometres from Mimas.
The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.
