Strangely enough KIC 8462852, a star 1,481 light-years away from Earth is behaving oddly demonstrating irregular, unnatural, flickering patterns. It exhibits extreme drops in brightness, up to 22 percent at one moment, and there appears to be no pattern to the lights. Researcher Bradley Schaefer believes the cause is from a swarm of comets. However historical data shows that the star's light has been fading for at least a century.
