In 2011 and 2013 the light shining from a distant star dropped by an unprecedented 20 percent, leading some astronomers to wonder if something very, VERY, big is blocking it from Earth’s view.
Star KIC 8462852, also known as ‘Tabby’s Star’, has been emitting an erratic flickering light, prompting great debate among the astronomy community as to what is obstructing our view of the star.
KIC 8463852 is located in the Cygnus constellation, about 1,480 light years from Earth.
Some say the star’s brightness has been gradually dimming over the last century, while others suggest that large comets or a huge dust cloud could be blocking the light. A number of people think a massive ‘alien megastructure’ is to blame.
