Record-breaking cosmic explosion detected by astronomers.

Astronomers have observed the largest explosion in space, called AT2021lwx, which has been ongoing for three years and is 10 times brighter than any known supernova. The explosion occurred 8 billion light-years away when the universe was 6 billion years old and is believed to be the result of a black hole violently disrupting a massive cloud of gas. The explosion's exceptional brightness is comparable only to quasars emitted by supermassive black holes. The researchers plan to study the explosion in different light wavelengths to understand its temperature and driving processes.
