An article under review for publication reports a study on the galaxy ESO 253-G003 that classifies it among the ones with an active galactic nucleus that is consuming a star orbiting the central supermassive black hole. A team of researchers led by Anna Payne of the University of Hawaii used observations conducted with various telescopes to study the phenomenon, cataloged as ASASSN-14ko, detecting a series of regular cosmic outbursts that were interpreted as energy emissions linked to the passage of a star too close to the black hole, which destroys a part of it at each orbit.
