Astronomers Observe Largest Cosmic Explosion in History.

Astronomers have captured the largest explosion ever seen, known as AT2021lwx, which is more than 10 times brighter than any known supernova and three times brighter than the most radiant tidal disruption event. The explosion, which has lasted over three years, was caused by a vast cloud of gas thousands of times larger than our sun that fell into the jaws of a supermassive black hole. The overall energy released was far greater than initially thought, and the only things in the universe that can match it are quasars. The team is now setting out to collect more data on the explosion to understand how the centers of galaxies change over time.
