Currently, the faint star V Sagittae, V Sge, in the constellation Sagitta, is barely visible, even in mid-sized telescopes. However, around the year 2083, this innocent star will explode, becoming as bright as Sirius, the brightest star visible in the night sky. During the time of this eruption, V Sge will be the most luminous star in the Milky Way galaxy. This prediction is being presented for the first time at the 2020 American Astronomical Society meeting in Honolulu, HI, by astronomers Bradley E. Schaefer, Juhan Frank, and Manos Chatzopolous with the LSU Department of Physics & Astronomy.
