After receiving the clearest photos ever taken of Saturn's moon Titan, scientists now believe there are oceans of liquid hydrocarbon found there. This would make Titan the only place in the solar system other than earth to have seas of open liquid.
Titan, which is larger than the planet Mercury, is also the only body in the solar system known to have high concentrations of nitrogen in the atmosphere, other than Earth. Scientists believe it may hold answers to the question of how life began.
Rain may even fall upon the giant moon, although the methane that makes up the drops would cause the rain to fall differently. A spacecraft is currently on its way to Saturn, reaching it in 2004, and intends to land on Titan's surface.
