Astronomers witness largest cosmic explosion in history of universe.
TL;DR
Astronomers have detected the largest cosmic explosion ever witnessed, called AT2021lwx, which is 10 times brighter than any known exploding star and has lasted for three years. The explosion occurred nearly 8 billion light-years away from Earth and is thought to have been triggered by a supermassive black hole disrupting a vast gas or dust cloud. The event dethrones gamma-ray burst GRB 221009A as the brightest recorded cosmic explosion. The research team wants to collect more data across different wavelengths of light to learn about the details of the event, including its temperature.
