New data debunks alien megastructure theory on mysterious “Tabby’s Star”

3 January 2018 Astronomy Now

A team of more than 100 researchers is one step closer to solving the mystery behind the “most mysterious star in the Universe.” KIC 8462852, or “Tabby’s Star,” nicknamed after Boyajian, is otherwise an average star. It is about 50 percent bigger and 1,000 degrees hotter than the Sun. It is more than 1,000 light-years away. However, it has been inexplicably dimming and brightening sporadically like no other. Several theories abound to explain the star’s unusual light patterns including an alien megastructure orbiting the star.

Breakthrough Listen to search for intelligent life around weird star

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.

Milky Way’s most-mysterious star is even stranger than astronomers thought

4 October 2016 Astronomy Now

A star known as KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year. In 2015 a team of astronomers announced that the star underwent a series of very brief, non-periodic dimming events while being monitored by NASA’s Kepler space telescope. A new study has deepened the mystery.

Kepler finds Tabby’s Star is mysteriously dimming

The so-called ‘most mysterious star in the galaxy’, also known as KIC 8462852, Tabby’s Star, the WTF (‘where’s the flux’) star and the ‘alien megastructure star’, has become even stranger according to new analysis of old observations from Kepler.

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.

Mysterious star remains silent on the SETI front

9 December 2015 Keith Cooper

A mysterious star that erratically dims by nearly a quarter as a swarm of unknown objects passes in front of it – leading to speculations that artificial objects could be orbiting the star – continues to refuse to give up its secrets after a search for laser pulses from the system turned up empty.

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?

Looking for artificial radio signals from star system KIC 8462852

6 November 2015 Astronomy Now

Could there be intelligent life in the star system KIC 8462852? A recent analysis of data collected by NASA’s Kepler space telescope has shown that this star — informally known as Tabby’s Star — displays large, irregular changes in brightness consistent with many small masses orbiting the star in “tight formation”. The SETI Institute trained its Allen Telescope Array on this star for more than two weeks in order to investigate the possibility of a deliberate cause of KIC 8462852’s unusual behaviour.
