Liquid Lakes confirmed on Titan!

Latest issue of Nature provides evidence that Ontario Lacus at Titan's South pole is definitely liquid.

I just wanted to call attention to the newly-released VIMS detection of Ethane within Titan's Ontario Lacus. Prior evidence for lakes, while compelling, was entirely circumstantial. The lakes look really dark in RADAR, and in ISS, and show lake-like morphologies. What we've found is the smoking gun that unambiguously identifies the lakes (well, this one at least) as being liquid, and composed at least partially of ethane. Presumably the ethane is in solution with liquid methane, but we can't identify methane since those lines are entirely saturated by looking through so much of it in the atmosphere.

Anyway, you can read either the press release or the paper in Nature. I've posted a copy of the paper on my website as well.

It has been mentioned elsewhere (and there is a great post on http://planetary.org/blog ), but thank you for posting the paper!
