Best evidence yet
*...for a shoreline on Titan; they're calling it "dramatic." Area measures 1,060 by 106 miles. Is from Cassini radar, obtained during the latest flyby. Speculation continues regarding seepage of liquid from the ground/ground springs and/or rainfall. |

Dark area on the radar image suggests the ground must be very smooth. Such dark regions have been searched since the first Cassini radar observations of Titan (remember the "Cat" feature from the first radar swath).
In dark areas very little scatters back to the detector. So dark regions are smooth (or in some cases slopes facing away from the probe). In brighter areas (which represent rougher terrain) there are a lot of scattering and radar echo is much better. One must remember that light and dark areas in radar images have nothing to do with visual brightness. Also, radar may penetrate the surface so some features we see may actually be underground. -------------------- The universe is not only stranger than we imagine, it is stranger than we can imagine.
