NASA's Cassini spacecraft buzzed Titan last year, coming close enough to taste the Saturnian moon's atmosphere.  The data acquired has implications for our understanding of life throughout the galaxy, as well as Earth's own past.

The second largest moon in the solar system, Titan has long been of interest for hopeful exobiologists.  As the only other body we know of with surface bodies of liquid, complete with nitrogen, methane and complete seasonal weather weather patterns (similar to Earth's).  It even has beaches, though you'll need a little more than a swimsuit to visit.  Vast bodies of chemicals constantly stirred by wind and wave, heated over a gentle sunlight heat with the occasional dash of articles from Saturn's magnetosphere for spice - a perfect recipe for life. Just like a certain planet you might be familiar with (look down if you forget).
