Planets around M-type stars and the rising potential of life beyond Earth

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 - A massive project to generate an all-color map of the galaxies in a small area of sky, utilizing four satellite telescopes and four ground-based telescopes, is yielding new information about the universe's "pre-teen" years and the early evolution of galaxies and galaxy clusters. See article. Note: This article is from 2007.
g Abodes - The changing view of planets orbiting low mass stars, M stars, as potentially hospitable worlds for life and its remote detection was motivated by several factors, including the demonstration of viable atmospheres and oceans on tidally locked planets, normal incidence of dust disks, including debris disks, detection of planets with masses in the 5–20 M_ range, and predictions of unusually strong spectral biosignatures. See article.
g Message - Nobody has yet seen an extraterrestrial, which may sound like a problem in establishing a science of astrobiology. But in the past 20 years or so, scientists have found clues that life may be quite common in the universe, and many are hopeful that they will soon find hard evidence of life beyond Earth. See article. Note: This article is from 2006.
