It was kind of unbelievable that it was real data,” said Yale University astronomer Tabetha Boyajian. “We were scratching our heads. For any idea that came up there was always something that would argue against it.”
She was talking to the New Scientist about KIC 8462852, a distant star with a very unusual flickering habit. Something was making the star dim drastically every few years, and she wasn’t sure what.
To Wright, it looked like the kind of star he and his colleagues had been waiting for. If none of the ordinary reasons for the star’s flux quite seemed to fit, perhaps an extraordinary one was in order.
Or, to be more specific, something built by aliens – a “swarm of megastructures,” as he told the Atlantic, likely outfitted with solar panels to collect energy from the star.
“When [Boyajian] showed me the data, I was fascinated by how crazy it looked,” Wright said. “Aliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilization to build.” […]
