Happy Titan Day

Happy Titan Day everyone!! Okay, not an official holiday, at least not for the next hundred years, but today is the 350th Anniversary of Christiaan Huygens' discovery of Titan. So drink some Titan ale and have some Xanadu Bread and enjoy the day.

UPDATE: The Astronomy Picture of the Day website is celebrating Titan Day by showing an image of the telescope lens used by Huygens to discover Titan, or as Huygens called it "Luna Saturni". They also have a great link to a Dutch website (in English) describing the circumstances of the discovery and the means by which Huygens announced it.
