Worlds with no suns may harbor life and why ETI isn’t tuning us in

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 - Astronomers have come up with a new way of identifying close, faint stars with NASA's Galaxy Evolution Explorer satellite. The technique should help in the hunt for planets that lie beyond our solar system, because nearby, hard-to-see stars could very well be home to the easiest-to-see alien planets. See article.
g Abodes - There may be worlds that float through intergalactic space in darkness without stars to warm them. Such lonely planets, endlessly adrift in night, might seem too cold and dark to ever serve as homes for life. But mysterious, unseen dark matter could help make warm these starless planets and make them habitable, a new study suggests. The idea may be a bit out there, but it’s not impossible, researchers say. See article.
g Life - Exotic life forms may be lurking in your home, and a new citizen science project seeks to find them. By sampling home water heaters to study the micro-organisms that thrive there, scientists can learn more about the types of life we may find beyond Earth. See article.
g Message - For more than 85 years, we’ve been sending radio (and eventually television) transmissions into space, allowing anyone in space to hear war reports from London, “I Love Lucy” reruns and our latest election results. So wouldn’t hearing aliens be as simple as turning on the radio? See article. This article is from 2004.
