Two news papers based on NASA's research propose that there may be life on Saturn's largest moon TITAN. While non-biological chemistry offers one possible explanation, some scientists believe these chemical signatures bolster the argument for a primitive, exotic form of life or precursor to life on Titan's surface. One persons theory says it may be "methane-based life."
One finding comes from the journal Icarus that shows hydrogen molecules entering down through Titan's atmosphere and disappearing at the surface. Another paper online now in the Journal of Geophysical Research maps hydrocarbons on the Titan surface and also finds a lack of acetylene.
It would be pretty cool to find life on another planet (or a moon) because that may mean in the far future people may move to that planet/moon.
