Comets ideal for life to form and ‘Societal Implications of Astrobiology’

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the habitable zone for the nearby star system Gliese 570 ABCD?
g Abodes - The watery environment of early comets, together with the vast quantity of organics already discovered in comets, would have provided ideal conditions for primitive bacteria to grow and multiply. See article.
g Life - Hundreds of astronomers recently learned that life in outer space is likely to lack green eyes and be far more prosaic, tiny and, quite possibly, completely unlike life as we know it. This blunt appraisal came from the University of Washington's Center for Astrobiology and Early Evolution, one of the first programs in the country to give an advanced degree in astrobiology. See article. Note: This article is from 2003.
g Cosmicus - New laser propulsion experiments are throwing light on how to build future hypersonic aircraft and beam spacecraft into Earth orbit. See article.
g Learning - Quote of the Day: “It is the fate of most voyagers, no sooner to discover what is most interesting in any locality, than they are hurried from it.” – Charles Darwin, “The Voyage of the Beagle”
g Aftermath - Here’s an intriguing read: the final report of the “Workshop on the Societal Implications of Astrobiology”. Note: The workshop was held in 1999.
