(No, I'm not talking about ocean liners hitting icebergs. That's not for another three weeks.)
Tomorrow, March 25, marks the anniversary of the discovery of Saturn's giant moon Titan in 1655. Titan was discovered by Christian Huygens, which of course is why the 2004 space probe to Titan was called the Huygens lander. Appropriately, the Cassini probe (which served as "mother ship" to the Huygens lander) is due to make a close approach to Titan tomorrow. Titan has been in the news lately because of indications that it may have a subsurface ocean. It seems like every two-bit celestial body has a subsurface ocean nowadays.
By a happy coincidence, the Strange Maps Web log has a nice post about a recently-discovered methane lake on Titan. Presumably one can sit on the shore and listen to some rather chilly Sirens.
