Continents on Titan?
Saint Aardvark writes: "CNN reports here that a second bright spot has been found on Titan. The speculation is that it's a continent, but scientists can't be sure until Cassini arrives at Saturn and drops the Huygens probe through the atmosphere."
Very true. But we're looking for life anywhere we think it's likely to appear, and optimists think that it will evolve anywhere with the right conditions.
Furthermore, I recall some crazy idea mentioned in Stephen Baxter's Titan, that life could exist there, based on nitrogen, ammonia and cyanide instead of oxygen, water and carbon dioxyde... Who knows? Not us, and that's why we're trying to get a look.
