Science -- Liquid Lakes Found on Titan

This appeals to the Planetary Scientist in me (ah, the days of wine and exogeology).

Basically, Cassini (the probe sent to Saturn many years back) has snapped pictures of Titan's surface, which show strong evidence of current liquid lakes on the surface. Titan is interesting because it's the only other terrestrial body in the solar system with an atmosphere as substantial as Earth's. The drawback is that Titan is incredibly cold, and the atmosphere (and lakes) are nearly entirely hydrocarbons. To quote from the CNN article below, "Scientists believe methane gas breaks up in Titan's atmosphere and forms smog clouds that rain methane down to the surface." [I think they may have meant ethane gas breaks up to form methane.]

So effectively, Titan is covered in lakes of ethane and methane, under a blanketing atmosphere of the very same. Fun stuff. Oh, by the way... uou may know ethane by another name... vodka. =P

Anyways, here's the article: http://www.cnn.com/2006/TECH/space/07/25/saturn.titan.ap/index.html
