What's the most likely place (other than here) in the Solar System to find life, according to scientists?  Nope.  No, not there either.

The answer is Titan, the smoggy, orange moon of Saturn.  It's the only moon around with a fully-developed atmosphere, and planetary observers have been intrigued with it for decades, because they believe that atmosphere may be rather like the one Earth had before we got the one we have now -- the one infested with life.  Of course, right now, Titan's air is mostly nitrogen and methane, probably smelling more like a Porta-Potty than an invigorating sea breeze.

Now, we have the Cassini-Huygens probe circulating through the Saturnine system of moons and rings. Today marks the first really close fly-by of Titan: only 750 miles up. Already it's spotted a strange, light-colored "continent" called Xanadu (but no stately pleasure domes, so far). That's been seen before with the Hubble Space Telescope, but this is our best chance yet to learn if the ethane lakes and proto-amino acids of scientific reverie are really there.
