Old stars in young universe, seashells prove evolution and personal spaceflight business

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 - An international team of astronomers based at Yale and Leiden University in The Netherlands found that "old stars" dominated many large galaxies in the early universe, raising the new question of why these galaxies progressed into "adulthood" so early in the life of the universe. See
g Abodes - NASA's Hubble Space Telescope has discovered 16 extrasolar planet candidates orbiting a variety of distant stars in the central region of our Milky Way galaxy. See http://www.astrobio.
g Life - When he started compiling an online database of seashells 15 years ago, Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. See
g Cosmicus - Those caught in the whirlwind of the personal spaceflight business—the builders, shakers, dreamers and schemers—will be found this month at the Wirefly X Prize Cup, set for Oct. 20-21 in Las Cruces, N.M. See
