A large cluster of objects in space look like something you would "expect an alien civilization to build", astronomers have said.
Jason Wright, an astronomer from Penn State University, is set to publish a report on the “bizarre” star system - suggesting the objects could be a “swarm of megastructures”.
He told The Independent: "I can’t figure this thing out and that’s why it’s so interesting, so cool – it just doesn’t seem to make sense."
Speaking to The Atlantic, Mr Wright said: "Aliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilisation to build. I was fascinated by how crazy it looked."
The snappily named KIC 8462852 star lies just above the Milky Way, between the constellations Cygnus and Lyra. It first attracted the attention of astronomers in 2009, when the Kepler Space Telescope identified it as a candidate for having orbiting Earth-like planets.
But KIC 8462852 was emitting a stranger light pattern than any of the other stars in Kepler’s search for habitable planets.
Kepler works by analysing light from distant places in the universe — looking for changes that take place when planets move in front of their stars. But the dip in starlight from KIC 8462852 does not seem to be the normal pattern for a planet.
Tabetha Boyajian, a postdoc at Yale, told 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.”
