Astronomers Witness Largest Cosmic Explosion in History

Astronomers have discovered the "largest" cosmic explosion ever observed, called AT2021lwx, which is 100 times the size of our Solar System and has been blazing in the distant universe for over three years. The explosion is estimated to be around two trillion times brighter than the Sun and is still blazing away. The most likely explanation for the explosion is that a massive, single cloud of gas is slowly being consumed by a supermassive black hole. However, more research is needed to understand the puzzling phenomenon.
