The Harvard physicist Paul Horowitz once said in an interview with Time Magazine, "Intelligent life in the universe? Guaranteed. Intelligent life in our galaxy? So overwhelmingly likely that I'd give you almost any odds you'd like." As yet, however, scientists haven't found it, but NASA's Astrobiology Program is certainly looking. This site gives readers insight into the search for life on other planets, as well as our current understanding of how life developed here on Earth. The About Astrobiology section provides an erudite overview of the field, and the frequently updated articles on the homepage are likely to inspire curiosity. One of the really unique offerings of the site is the section entitled, Ask an Astrobiologist. Here, readers can Submit a Question to astrobiology experts or peruse previously Answered Questions.
