Extraterrestrial Mapquest

Lio by Mark Tatulli.  For those who may not know, Gliese 581 c is one of the more famous of the 500 or so newly discovered planets outside our solar system.  The Gliese 581 system, in fact, contains at least 6 known planets.  Gliese 581 initially seemed to be habitable, prompting Lio's desire to make the trip.  However further evidence showed it to be less likely to sustain life. Rather , its sister planet Gliese 581 g, at only 1.9 x the mass of Earth, and residing within its star's "habitable zone",  appears to be the better candidate for supporting life.
