It has baffled astronomers since it was first discovered in 2015, but now experts believe they may be one step closer to solving the mystery of Tabby’s star.

The star, otherwise known as KIC 8462852, is located 1,400 light years away.

It dims at a much faster rate than other stars, which some experts have suggested is a sign of aliens harnessing the energy of a star.

But a new study ‘eliminates the possibility of an alien megastructure’, and instead, suggests that a ring of dust could be causing the strange signals.

Researchers from the University of Arizona have submitted a new study which refutes the idea that the staggering dimming of Tabby’s star is caused by aliens.

The researchers collected observational data of Tabby’s star from October 2015 to March 2017 from two Nasa telescopes – Swift, which takes X-ray and UV measurements, and Spitzer, which measures objects in infrared.

Speaking to Inverse, Huan Meng, lead author of the study, said: ‘We found that from UV, throughout the visible spectrum, to IR, the star is dimming at every wavelength we monitored.’
