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.

Several theories abound to explain the star’s unusual light patterns including an alien megastructure orbiting the star.
