A large lake found on Saturn’s moon, Titan, has very similar features to the Etosha Pan, a salt marsh, located in the north of Namibia, which at times filled with water. It may well be that the "big lake" on Titan, too, by its very nature temporary.
Lake Ontario Lacus, so named in view of its similarity in shape and size to Lake Ontario, existing on Earth, it was discovered the Cassini spacecraft for the first time in 2009 near the south pole of Titan. On a dark slightly blurred image of the radar is a uniform that reflects the light surface, which looks more like a shallow, large fluid space.
Certainly, the liquid on Titan is not water but methane, which is the main element gidrolicheskogo cycle, the researchers found that the giant satellite. Since the satellite is a far cry from the normal temperature of the sun on the pole of Titan is minus 185 ? C, and at such a low temperature water can not exist, so in this world took its place methane.
A research team from the University of Thomas Cornet of Nantes in France, examined in detail all the pictures Ontario Lucas made Cassini radar and found some evidence of the existence of embedded channels in the southern part of the lake. According to the researchers, etou shows that the surface of the lake is completely open.
"We believe that the solid ground of Ontario Lucas likely disclosed in places where the infeed channels."
Meanwhile, the sedimentary rocks are around the lake, some suggest the liquid level fluctuations in the lake.
