"However, if cells weren't based on water but on methane—which has a much lower freezing point—could “life” exist in extremely cold worlds like Saturn’s moon Titan? The giant moon is spotted with seas of liquid methane and has no oxygen available for the formation of a lipid bilayer membrane."

Well, given we have some lifeforms on THIS planet that can live in methane rich environments (and use methane for energy, not simply able to survive, but still need oxygen), I figure that's not a deal breaker far as there being life on Titan.

But, they still require oxygen; in this case, we'd be talking about more complex methane-based life forms.

Only way to answer the question is to send more probes there.

I remember watching live when Hyugens touched down. Was my own Moon landing I suppose, since before then we'd never seen the surface. Well, at the time we had scans from Cassini (which brought Hyugens to Titan), but we'd still never glimpsed it visually.

I wonder what different forms methane based life could hypothetically take. And if methane based life forms are a possibility then what other kind of life forms could exist throughout the universe? It raises a lot of questions.
