The basic approach is simple: planets that are exclusively illuminated by a local sun will have one “light signature,” while a planet with artificial lights will have another. Loeb and Turner say that this technique, with our current telescopes, would be able to pick out a major terrestrial city on the edge of the Solar System, in the Kuiper belt (50 AU) — but future telescopes, or the telescopes belonging to advanced, alien races, could see farther.<br/> <p><strong>Tags:</strong> #aliens #civilizations #science #space</p> Tue, 01 Nov 2011 21:20:33 +0000 linkding-ssg:bookmark:19292 aliens civilizations science space
