Possible Methane Lakes on Titan

Have methane lakes been discovered on Saturn's Titan?

That exciting possibility was uncovered from analyses of
radar images
returned last week by the
robotic Cassini spacecraft
now orbiting Saturn.

that the dark areas might be pools of liquid
includes an extreme smoothness implied by the lack of a return
radar signal, and apparently connected tributaries.

If true, Titan would be only the second body in our
Solar System, after
Earth, found to possess liquids on the surface.

Future observations from Cassini during
Titan flybys might test the
methane lake hypothesis,
as comparative wind affects on the regions are studied.
