Our commonplace sun and what makes Earth habitable

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 - The most comprehensive comparison of our sun with other stars has shown that there is nothing 'special' about the sun. The findings add weight to the idea that life could be common in the universe. See article.
g Abodes - What makes Earth habitable? This LiveScience original video explores the science of global warming and explains how, for now, conditions here are just right. See article.
g Life - New research conducted by the MARTE project team has shown that microbes can make barren areas suitable for life. This could have important implications for the search for life on Mars and other planets. See article. For related article, see “Life Found Where You Least Expect It”.
g Message - Quote of the Day: “The stars … blindly run;/A web is wov’n across the sky;/From out waste places comes a cry” – Lord Alfred Tennyson, “In Memoriam, A.H.H. III”
g Cosmicus - Technology that could someday provide 3D roadmaps of other planets and moons is now in development. The information the maps provide would help in designing future scientific missions to locations in the solar system. See article.
g Imagining - Are there any alternatives to DNA or RNA, as an "X-Files" episode said there was? See article.
