This is the latest website from the Exploratorium's _Origins_ series -- a Web-based project that "explores the origins of matter, the universe, earth, and even life itself." In "Astrobiology: The Search for Life," visitors can read up on Earth's extreme environments that support life and serve as models for extraterrestrial environments. The site also introduces some of the scientists working in astrobiology, including Jill Tarter. Other sections explore the tools of the trade (e.g. NASA's Mars Rover) and important ideas in astrobiology (e.g. the Drake Equation). Additionally, during the month of November, the Exploratorium will air live webcasts from field sites like Chile's Licancabur volcano, and broadcast interviews with some of astrobiology's top brass.
