This composite was produced from images returned 14 January 2005 by ESA's Huygens probe during its descent to land on Titan. It shows the boundary between the lighter-coloured uplifted terrain, marked with what appear to be drainage channels, and darker lower areas. These images were taken from an altitude of about 8 kilometres with a resolution of about 20 metres per pixel. Credits: ESA/NASA/University of Arizona. Click to enlarge.
