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. |

From Ralph Lorenz's very short abstract "The Surface of Titan", from this May's "Planetary Science: Discoveries and Challenges" conference in France:
"A global circulation model suggests Titan's equatorial regions should be dry, while high latitudes are saturated. The detection by Cassini RADAR of sand dunes near the equator, and an apparent coastline at high latitude, are consistent with this picture." Of course, this doesn't necessarily mean there's much methane rain even in high latitudes -- just more than in the equatorial region. But it does mesh well with the picture of Titan that John Rehling keeps giving us. |
