Astronomers witness largest explosion in the universe.

Astronomers from the University of Southampton have discovered the largest cosmic explosion ever seen, known as AT2021lwx, which is more than ten times brighter than any known supernova and three times brighter than the brightest tidal disruption event. The explosion has lasted over three years and is believed to be a result of a vast cloud of gas violently disrupted by a supermassive black hole. The explosion took place nearly 8 billion light years away and is still being detected by a network of telescopes.
