Life in dormant hydrothermal vents and ice on asteroid Vesta

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 - A Naval Research Laboratory scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth. The scientists are studying the hot (30 million degree) gas using X-ray data from NASA's Chandra X-ray Observatory and optical data from the Very Large Telescope to see the galaxies. See article.
g Life - Scientists have discovered evidence that life continues at hydrothermal sea vents, even after the vents themselves go dormant. The study sheds light on how microbial communities survive in one Earth's most unique environments. See article.
g Intelligence - Neuroscientists may one day be able to hear the imagined speech of a patient unable to speak due to stroke or paralysis, according to University of California, Berkeley, researchers. See article.
g Cosmicus - Half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could survive. See article.
