A view of Titan from the Cassini orbiter (outer areas) is overlaid by an image from the Huygens probe (center), which landed in the small red circle on the boundary of the bright and dark regions. The size of the circle shows the field of view of the Huygens DISR imager from an altitude of 20 kilometres. Credit: ESA/NASA/JPL/University of Arizona. Click to enlarge.
