(Newser) – Something is sucking up hydrogen on one of Saturn's moons and NASA scientists believe it could be alive. Data from the Cassini probe suggests there is less hydrogen and acetylene on Titan's surface than scientists expected, a phenomenon that could be explained by the existence of primitive, methane-based lifeforms, the researchers write.

"We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth," one of the astrobiologists says. "If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."
