"Strange, New Worlds"
Here's an article about NASA's new project to develop computer simulated models of what kinds of planets could support water/light based life, to be used as a referential database when they send their new set of deep-space probes to start exploring and cataloging planets with possible neighbors. Too bad that they're just looking for life as we know it on earth, rather than sentience, which may not necessarily be carbon-based. "Baby steps", as they say.
