The Lakes of Titan

Photo Credit: NASA
For those of you that haven't seen this amazing photo, this is not a photo of Earth, but is instead an enhanced image of the lakes in the northern hemisphere of Titan, one of Saturn's moons.  NASA reports that the data for the above image was taken by the Cassini Orbiter during a close flyby of Titan on September 12, 2013, and that the image is actually a false-color mosaic made from infrared data.  The hydrocarbon lakes are believed to be made of liquid ethane and methane.  Titan is the only other body in the solar system known to have a stable liquid weather system on its surface.  For more information about the above image and about the lakes on Titan see NASA's "Titan's Northern Lakes: Salt Flats?" and "Cassini Gets New Views of Titan's Land of Lakes."
