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.
Supernovae, the explosions of stars, have been observed in the thousands and in all cases they marked the death of a star. Astronomers at Las Cumbres Observatory have discovered a remarkable exception — a star that exploded multiple times over a period of more than fifty years. Their observations are challenging existing theories on these cosmic catastrophes.
