Liquid Lakes confirmed on Titan!

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

Thanks Jason for that link to the Nature paper.....

This news article has some great VIMS images of the beach at Ontario Lacus.

Does VIMS have a site with updated image products?

I've walked the beaches of the Great Lakes (live near Lake Erie). Would love to walk this beach.

Hey wow, that color one is one of mine, I think. Cool. Didn't realize that the European release was distinct.

Regarding the Beach, although we call it that, I don't think that it really is a beach. Geologists define a beach as "wave deposited sediments", which I'm not convinced these are. Standby for more on this; just submitted a paper to Icarus last week about what it and the outer, bright ring might be and what that means.

Or better yet, stand by for T49 when we will get altimetry on it. My guess is the whole thing
('beach' and all) will be 10^-3 or lower slope (i.e. a tidal flat) but we will see a radiometric
transition where the present 'waterline' is (presumably the residual ethane - with some amount
of methane having seasonally evaporated)

Of course, RADAR data is merely 'circumstantial' per your earlier post, maybe that isnt of
interest mad.gif ....
