Astronomers Could Soon Find Moons Outside the Solar System--Even Habitable Ones: Scientific American

Interesante nota sobre nuevos planetas: Astronomers Could Soon Find Moons Outside the Solar System--Even Habitable Ones: Scientific American. Me gustaria saber si hay algun buen libro de ciencia ficcion basado en los ultimos descubrimientos! Es bueno el comentario de que la ciencia en Avatar esta atrasada al menos 7 años, con respecto a localizaciones de planetas similares a la Tierra: "What's interesting is Avatar is out of date by about seven years," Seager says. Astronomers have looked for the presence of giant planets in the habitable zone of Alpha Centauri, the nearby star system that is home to Pandora in the film, and have not found one. That's not to say that Alpha Centauri doesn't have a habitable world of some kind—it would just have to be a planet like our own, rather than a moon. "If they had called me or someone else in exoplanet astronomy," Seager says, "we would have advised them to just put an Earth there."

Me pregunto si la gente que mantiene la base de conocimientos de Star Wars la actualiza como corresponde!
