The University of Southampton’s astronomers recently reported the discovery of the largest cosmic explosion that emits an astronomical amount of energy for over three years. AT2021lwx, located almost eight billion light-years away, is ten times brighter than any supernova and three times brighter than the most radiant tidal disruption event known. The explosion is equivalent to 100 times the size of our solar system caused by the violent disruption of a massive gas cloud by a supermassive black hole. Discovered by the Zwicky Transient Facility, the explosion has lasted for an unusual length and, as such, piqued the interest of the global scientific fraternity. Following the investigation using several telescopes, astronomers calculated its distance and brightness, which proved to be unprecedented, and suggested it could be a fundamental trigger for the center change of galaxies.
