Tabby’s star, otherwise known as KIC 8462852, has provoked so much excitement over the past year, with speculation that it hosts a highly advanced civilisation capable of building orbiting megastructures, that UC Berkeley’s Breakthrough Listen project is devoting hours of time on the Green Bank radio telescope to see if it can detect any extraterrestrial signals.
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.
A star called KIC 8462852 has been in the news recently for unexplained and bizarre behaviour. NASA’s Kepler mission had monitored the star for four years, observing two unusual incidents, in 2011 and 2013, when the star’s light dimmed in dramatic, never-before-seen ways. Something had passed in front of the star and blocked its light, but what?
