DARMSTADT, Germany -- The first pictures revealing the surface of Saturn's moon, Titan, were shown from Europe's Huygens probe showing what look like drainage channels on the surface of what until today has been a planet totally hidden from view.

The first image, taken from an altitude of 16 kilometers, has a ground resolution of about 40 meters, said Martin Tomasko, principal investigator for Huygens' Descent Imager/Spectral Radiometer (DISR). Tomasko said that Huygens research teams now have about 350 pictures to work with. [Scroll to the bottom of this story to see raw image files of the Titan descent taken by Huygens.
