Possible life in Space

I was reading through USA Today's website and came across a space related article predicting possible life on Saturn's moon Titan. Its a neat piece which explains that recent satellite photographs have shown that some sort of liquid is often present on the surface of this moon. This liquid may not be water, however the simple fact that it is there has lead scientists to wonder what exactly it is, and how it got there.
