Planetary habitable zones, surface conditions of extrasolar planets and lunar record of Earth’s climate

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 - Astronomers have determined how far away from its hot stellar neighbors a star must be if a swirling disk of dust around it is to stand a chance of forming planets. See http://www.livescience.
g Abodes - The weather and surface conditions of planets outside our Solar System could be detected by constellations of telescopes sent to space, and then used to predict which are most Earthly and likely to harbor life, according to new research. See http://www.space.

g Cosmicus - Research has shown that surface temperatures on the near side of the Moon may provide an accurate record of information concerning the Earth's climate. Consequently, monitoring stations on the Moon could one day help us study our own planet. See http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid=2354&mode=thread&
g Learning -Quote of the Day: “Who could have imagined that our quest to decode the mysteries of the universe, armed with a myriad of artificial senses, would grant us insight into ourselves?” — Neil De Grasse Tyson
