When the Cassini-Huygens mission parted Titan's smoggy veil, it revealed a

Titan's frozen terrain, but in this interview with Astrobiology Magazine, David
Grinspoon ponders whether life could exist there today.

Titan's Keys
http://www.astrobio.net/news/article1717.html

Saturn's moon Titan has long been a place of interest to astrobiologists,
primarily because of its apparent similarities to the early Earth at the time
life first started. A thick atmosphere composed primarily of nitrogen and
abundant organic molecules (the ingredients of life as we know it) are among the
important similarities between these two otherwise dissimilar planetary bodies.
