Titan, the largest moon of Saturn, is notably the only known extraterrestrial body where surface liquid exists. In its case, the liquid is not water but rather liquid methane. Titan hasn't just got a few puddles here and there, either: it has veritable seas of liquid methane covering large parts of its surface. And at a balmy -180 degrees Celsius, they make for the perfect beach vacation!
Recently, scientists have been puzzled by th
e appearance of a large object in one of Titan's methane lakes:

Personally, I prefer to believe that the Sirens of Titan are somehow involved. At any rate, you can read more here.They spotted the object in an image taken by Nasa's Cassini probe last year as it swung around the alien moon, more than a billion kilometres from Earth. Pictures of the same spot captured nothing before or some days later.Little more than a white blob on a grainy image of Titan's northern hemisphere, the sighting could be an iceberg that broke free of the shoreline, an effect of rising bubbles, or waves rolling across the normally placid lake's surface, scientists say.Astronomers have named the blob the "magic island" until they have a better idea what they are looking at.
