Caption

Watch as a monster black hole partially consumes an orbiting giant star. In this illustration, the gas pulled from the star collides with the black hole's debris disk and causes a flare. Astronomers have named this repeating event ASASSN-14ko. The flares are the most predictable and frequent yet seen from an active galaxy.
