A new study of the enigmatic 'alien megastructure' star seems to have  solved the mystery and suggests that ETs are not to blame for its odd  dimming effect.

The puzzling star first came to the world's attention back in October of 2015 when scientists noted that it was inexplicably dimming and posited that  an alien structure of some kind could be the reason why.

By virtue of that exotic hypothesis, KIC 8462852, as it is known scientifically, sparked the public's imagination and led to a variety of attempts to unlock the mystery of its weird luminosity.

And now the results from a lengthy research project looking at the star  may have have cracked the case once and for all or, at least, eradicated  aliens from the equation.

Researchers observing the star for nearly two years were able to capture  data from four instances of KIC 8462852 as it dimmed and the insights  were illuminating.
