g ABODES - Scientists studying the chemical composition of comets have determined that they contain missing ingredients needed for life on the primordial Earth. The study lends weight to the idea that cometary impacts played an important role in the origin of life. See article.
g COSMICUS - As the president prepares to name a new NASA head, the agency is using Twitter to shape its reputation with contributions from astronauts and others. See article.
g IMAGINING - The secrets of the universe remain a mystery to us, but that doesn't stop us from making guesses. An author who writes a science fiction novel tries to base it around the technology and knowledge that we have available to us. Those tidbits of knowledge are then exaggerated to great lengths, and then set into the future, on other planets, in other dimensions in time, or under new variants of scientific law. This process is called extrapolation, and becomes the premise of the story. Here's a Web site that works in reverse, by taking the scientific aspects from classic works of science fiction and explaining how they relate to astrobiology.
g AFTERMATH - Here's an interesting book for some astrobiological reading: "After Contact: The Human Response to Extraterrestrial Life" by Albert A. Harrison. See reviews.
