Potential Sign Of Alien Civilization

"Planet Hunters," an amateur astronomer's group who studies data and records from NASA's Kepler Telescope has recently discovered a very unusual star. This star they discovered is located between the Cygnus and Lyra constellations above Milky Way. The star is called "KIC 8462852," and has a strange flickering light habit. Every couple of years, something happens to make the star's light dim and then brighten again. Scientists believe the flickering could be due to a natural occurrence, but the possibility of the flickering being due to extraterrestrial activity has not been ruled out. The University of California Berkley's SETI (Search for ExtraTerrestrial Intelligence) Group is now studying the star as well and scanning it for radio frequencies.
