City lights could reveal alien civilizations | ExtremeTech

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.
