Scientists also thought that the dark regions on Titan's equator were in fact seas of liquid ethane that trap sand. But the images reveal something different. "If you look at the dunes, you see tidal winds might be blowing sand around the moon several times and working it into dunes at the equator," Lorenz said. "It's possible that tidal winds are carrying dark sediments from higher latitudes to the equator, forming Titan's dark belt."So does this mean there aren't seas of liquid ethane on Titan? I wonder how that affects the chances of finding any kind of life there (not that it was ever a really good bet to begin with, I'm sure).
