How stars affect planet habitability and deciphering our thoughts on alien life

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 - Just how rare life is in the Universe is one of the key questions in the natural sciences today. By pulling in multidisciplinary expertise from biology, geology, physics and astronomy, astrobiologists are addressing different facets of this very profound question, and notably how the conditions around different types of stars in an early stage of development might help or hinder the emergence of life in a solar system. Several scientists at the forefront of this research have just concluded IAU Symposium 264 on "Solar and Stellar Variability - impact on Earth and Planets". See article.
g Abodes - The surface of Saturn's moon Titan has many features that appear similar to Earth, such as lakes, weather and mountains. Scientists even wonder if Titan could harbor a prebiotic chemistry that is similar to the early Earth when life first arose. See article.
g Life - Some critical steps towards finding life on Mars may have already been taken in the Tableland Mountains of western Newfoundland. See article.
g Cosmicus - Richard B. Hoover, Astrobiology Group Leader at NASA's Marshall Space Flight Center in Huntsville, Ala., is the 2009 recipient of the Gold Medal of SPIE, the Society of Photo-Optical Instrumentation Engineers. See article.
g Aftermath - Here’s an intriguing article: How SETI is using the social sciences to decipher our thoughts on alien life. See article. Note: This article is from 2002.
