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."
