Lakes on Titan?

Emily Lakdawalla from the Planetary Society blog has what might turn out to be a major scoop: possible liquid lakes on Titan! It's been thought for some time that liquid might exist on Titan, and given its dense atmosphere that's loaded with hydrocarbons, methane or ethane is a good guess. But evidence has been scant. The best so far was when the Huygens probe, launched by Cassini to land on Titan, appeared to have squished down in mud! But new evidence has just arrived. Emily posted the image above, taken using the Cassini probe's radar. It's the shape of the features that's interesting: sharp-edged, yet with rounded contours. That, plus the fact that liquid methane and ethane absorb radar, making them look dark just like those features, is very provocative. Emily reports that Cassini scientists are excited about the images, so I'm sure we'll be hearing lots more about this ...
