Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Stars - What is the habitable zone for the nearby star Lacaille 8760?
g Abodes - Scientists have discovered a potentially Earth-like planet around a star 30 light years away. At a size five times larger than Earth, it is the smallest extrasolar planet yet discovered. See article.
g Life - What is life? According to Sohan Jheeta, an astrobiologist from the Open University in Milton Keynes, UK, biologists have spent far too long dithering about how to define what a living organism actually is. As a result there are more than 280 definitions of life on record, and none of them really hits the mark, Jheeta says. See article.
g Message - Astronomer Michael M. Davis checked his computer. One of the antennas on the state-of-the-art radio telescope being built in the valley outside his office was picking up an unusual pulse from beyond the Earth. A signal from another intelligent civilization? Not today. It was the Rosetta Satellite, en route to study a comet. See article.
g Cosmicus - NASA has launched the new Lunar Science Institute to lead the agency's research activities for future missions to the moon related to NASA's exploration goals. See article.
g Imagining - Could the legendary dragons of Pern from Anne McCaffrey’s famous science fiction novels actually exist? Welcome to the theoretical science of dracogenetics. See article.
