Natural causes, not aliens, explain mystery star’s behaviour

Media interest went viral last October when a group of astronomers from Pennsylvania State University cited that the “bizarre light curve” of KIC 8462852, popularly known as Tabby’s star, was “consistent with” a swarm of alien-constructed megastructures. Now, the results of a new study make it far less likely that KIC 8462852 is the home of industrious extraterrestrials.
