The biggest explosion in the universe – level 3
Astronomers have witnessed the largest cosmic explosion ever recorded, originating from 8 billion light years away.
The explosion, called AT2021lwx, is more than 10 times brighter than any known supernova and is estimated to be a fireball 100 times the size of the solar system, with a brightness of about 2 trillion times that of the sun. Scientists believe that the explosion was triggered by a vast cloud of gas being sucked into a supermassive black hole. This cloud of gas, possibly thousands of times larger than our sun, may have come from the large dusty “doughnut” that typically surrounds black holes.
The explosion has so far lasted more than three years, making it the most energetic explosion ever recorded.
