This explosion continued and lasted for three years and occurred at a distance of 8 billion light years
Astronomers have discovered the largest cosmic explosion ever recorded, more massive and continuous than any known supernova, as it is estimated that a black hole swallowed up a cloud of gas.
The cosmic event, called AT2021lwx, occurred 8 billion light-years from Earth, when the universe was 6 billion years old, and was ten times brighter than any exploding star (supernova) event documented so far.
An additional advantage of this explosion is that it lasted three years, compared to the majority of (supernova) incidents that maintain its brightness over only a few months. Astronomers detected the explosion for the first time in November 2020, but it can be distinguished using a telescope until today.
However, this is not the brightest event ever recorded. Last year, astronomers were able to see a burst of gamma rays called GRB 221009A, but it only lasted a few minutes.
“According to our estimates, it is a fireball 100 times larger than the size of the solar system with a brightness equivalent to twice that of our sun,” said Dr. Philip Wiseman of the University of Southampton in England, who led the research team that followed the cosmic event. “For three years, this event released an amount of The energy is about a hundred times greater than that which the Sun will release every ten billion years of its life cycle.”
The research team tried to determine the cause of the accident. According to astronomers’ theory, a supermassive black hole swallowed a massive cloud of gas, sending shock waves across the universe and leaving behind a boiling remnant of the cloud around the black hole.
