Dramatic dimming of a distant star could be evidence of intelligent aliens

Kepler Space TelescopeKepler Space Telescope A star called KIC 8462852, known as "Tabby's Star", lying approximately 1500 light years away from Earth, is displaying a strange pattern of dimming. A long period of gradual fading has been punctuated by two dramatic drops in light, followed by instant rebounds, spaced nearly two years apart. Astronomers have already ruled out a number of natural explanations, leaving open the suggestion that the signals could be caused by giant structures built near the star by extraterrestrials—perhaps a giant array of orbiting solar panels.

Kepler finds them by searching for the small dip in the light triggered whenever a planet passes in front of the star
