‘Alien megastructure’ could explain mysterious new Kepler results

Strange signals from a distant star are defying natural explanation. There is a remote chance that they could be from an 'alien megastructure'

There's a new mystery in the universe and it goes by the name KIC 8462852. It is a star approximately 1500 light years away from the Earth, and displays a strange pattern of dimming that has astronomers scratching their heads.

With many natural causes apparently ruled out, there is even the suggestion that the signals could be caused by a giant structure, built in space near the star, presumably by extraterrestrials.
