Habitable zone of Groombridge 1618 and bacteria found 2 miles inside glacier

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 of the nearby star Groombridge 1618?
g Life - A novel, ultra-small bacterial species has been found at a depth of nearly two miles within the ice of a Greenland glacier. The ability of this organism to survive in such a unique environment will help us understand how life could survive elsewhere in the solar system. See article.
g Message - SETI and the University of California at Berkeley decided they needed their own instrument, so they started developing the Allen Telescope Array. See article.
g Cosmicus - Using Earth-based radar, scientists have studied ejecta material from the moon's Orientale impact basin. The new data has implications for future robotic and human missions to explore the lunar south pole. See article.
g Learning - Matt Levit is cautious. The 20-year-old doesn't drive, and he's never been on a plane. But Sunday, he will fly to the Search for Extraterrestrial Intelligence Institute on the West Coast to study astrobiology. See article.
g Aftermath - Here's an interesting book for some astrobiological reading: "After Contact: The Human Response to Extraterrestrial Life" by Albert A. Harrison.
