Sizes have been added to indicate scale of the features in this image of Titan's surface. The two rock-like objects just below the middle of the image are about 15 centimetres (left) and 4 centimetres (centre) across respectively, at a distance of about 85 centimetres from Huygens. The surface is darker than originally expected. Credits: ESA/NASA/University of Arizona. Click to enlarge.
