Four percent of galaxies similar to ours and Optical SETI

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 - New research shows that only four percent of galaxies are similar to the Milky Way. See article.
g Life - A new synchrotron X-ray technique could revolutionize chemical analysis of rare materials like meteoric rock samples and fossils. In doing so, astrobiologists could get a new glimpse into the origins and evolution of life on Earth. See article.
g Message - For many years the microwave Search for Extra-Terrestrial Intelligence held the spotlight, while the number of optical SETI observatories on this planet could be counted on the thumbs of one hand. Since a recent Optical SETI Conference, however, that has begun to change, with optical SETI finally emerging into the scientific mainstream. Advancing technology is only partly responsible for OSETI's change of fortune. See article.
g Cosmicus - Advanced textiles could the key to making human Mars missions a reality. Human explorers on Mars could play a major role in the search for signs of past or present life on the red planet. See article.
