Titan's surface. Cassini spacecraft image, taken through near infrared filters, of the surface of Saturn's moon Titan. The larger image shows a 2,000 kilometre wide area of dark and bright terrain. The bright areas are thought to be rough terrain, with the darker areas being smoother terrain. The smaller shots show details of the larger shot. The dark ring at the top of the smaller images is a camera artifact. The image at upper left shows dark and light bands spanning east to west (upper left to lower right). The middle and upper right images show very narrow long dark bands, measuring 2 kilometres across. Images taken during Cassini's flyby on 27 October 2004 at an altitude of 340,000 kilometres.
