A few weeks ago, scuba divers in Lake Tahoe found the body of a man who had drowned in the lake 17 years ago. Still in its wetsuit, the body was very well preserved. Because the water in this high alpine lake is so cold, decomposition is very slow. This fact has spawned rumors, the most famous of which involves Jacques Cousteau and still makes me shudder, years after I first heard it.
In a literal flash of insight, NASA's Cassini spacecraft has confirmed the existence of lakes of liquid in the Northern Hemisphere of Saturn's moon, Titan.
