Space travel amid the outer planets may one day depend on Titan's methane lakes and rivers.

The number of methane lakes visible near Titan's southern pole is decidedly smaller than the number observed near the north pole.

In the past, some have suggested that the methane lakes near the northern pole may only be more abundant during the winter.

A "warm" wind, or a break in the clouds--and the methane lakes will flash suddenly into vapor.

Saturn's moon Titan has a 60,000-year cycle that changes the location of the methane lakes.

Johnny lived far out on a glass-floored wing above a methane lake.

Although there is evidence of stream erosion near the equator, the moon's methane lakes are located near the poles-primarily the northern pole.

Areas named Lacus are believed to be methane lakes.

Koitere Lacus, one of the apparent methane lakes on Saturn's moon Titan is named after this lake.

And third, I'd like to float a boat on the methane lakes of Titan.
