READ MOREWhen they studied the star, which sits some 1,480 light years from Earth, they noticed a swarm of objects surrounding it in an usual pattern.
At first it was thought to be comets, shrapnel from an asteroid impact or even a mistake in the data but astronomer Jason Wright from Penn State University offered a more science fiction explanation.
Wright believes it could be an 'alien megastructure' designed to harness energy from the star.
"Aliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilization to build."
The post doctoral researcher at Yale says that the light being emitted by KIC 8462852 is what triggered some interest in 2011.
She explained to The Atlantic : "We’d never seen anything like this star It was really weird. We thought it might be bad data or movement on the spacecraft, but everything checked out.” ■
