Study: Glowing city lights might reveal E.T. civilizations

• Terrence Aym
The space telescope Kepler has identified more than 1,200 Earthlike planets to date. Some of them might support intelligent life. Avi Loeb of the Harvard-Smithsonian Center for Astrophysics and Edwin Turner of Princeton University believe the best way to find that life would be a systematic search for the glow of cities on the night side of exoplanets. In a paper—"Detection Technique for Artificially-Illuminated Objects in the Outer Solar System and Beyond"—published on Cornell University's website and in Astrobiology, the two scientists outline an intriguing plan to detect signs of artificial illumination as a means of finding intelligent extra-terrestrials.
