Over four years of observational data, KIC 8462852 flickered erratically, its light output sometimes dropping by as much as 20%. That’s highly unusual stellar behavior, and it can’t be explained by a transiting planet.Some astronomers proposed that KIC 8462852 might be occluded by a swarm of comets. Others suggested aliens…’

At its heart is an object a little larger than 10 miles across. And astronomers are not entirely sure what it is. If, as they suspect, the gas ball is the result of a supernova, then it’s the most powerful supernova ever seen…’
