On October 9, 2022, a cosmic explosion unleashed a radiation pulse that was extraordinarily bright and prolonged. A gamma-ray burst (GRB) occurred. They are the strongest explosions that the universe has ever seen. GRB 221009A, which occurred that day, was the brightest of its kind. As a result, it was the biggest explosion that has occurred since the Big Bang.
A study that was published on Wednesday in the journal Science Advances suggests that scientists may finally understand what made the GRB so bright.
GRBs, which are the most ferocious and catastrophic explosions in the universe, are known to release as much energy in a few seconds as our Sun will create over the course of its entire lifespan. GRB 221009A, commonly known as BOAT or the brightest object ever observed, was thought to be the result of a huge star slamming into a black hole, according to scientists. Many gamma-ray instruments in orbit were practically rendered blind by it, making it impossible for them to gauge its real intensity.
According to study co-author and physics professor at George Washington University Alexander van der Horst, experts have long believed that these jets have an ice cream cone-like structure. But new research on GRBs, particularly the BOAT study, indicates to astronomers that more complicated models and thorough simulations of the jets of these enormous explosions are required.
