Scientists say Saturn's largest moon, Titan, is an exotic world with Earth-like physical features, doused with rains of liquid methane.
In Paris Friday, European Space Agency officials said Titan has a complex network of narrow drainage channels merging into rivers and small oceans.
They say there is strong evidence liquid methane has carved up the surface, similar to the erosion that occurs by rainfall on Earth.
The team of scientists say the moon's thick nitrogen and methane atmosphere is possibly undergoing chemical reactions similar to those that unfolded on Earth billions of years ago.
Space agency officials say they will be studying the data taken from the Huygens space probe. The probe landed on the icy moon last week, after an eight-year journey aboard the Cassini spacecraft.
