On October 9, 2022, the most powerful gamma-ray burst in history was recorded. The outburst was designated GRB 221009A and disturbed the upper part of our planet’s ionosphere, which has never happened before.

The most powerful gamma-ray burst in history created a black hole and hit the Earth

Scientists were able to find a link between the gamma-ray burst and the reaction of the Earth’s ionosphere more than 40 years ago. The flare sent a stream of high-energy particles toward our planet, which disturbed the electromagnetic field.

Similar cases have been recorded repeatedly, but not above 350 km. But the gamma-ray burst of GRB 221009A shook the Earth’s ionosphere at an altitude of about 500 km. The flash lasted 7 minutes, but the electromagnetic field disturbance lasted several hours.

The GRB 221009A event occurred at a distance of approximately 2.4 billion light-years from our planet. Scientists believe that the burst was the result of a supernova explosion and the birth of a black hole. The flare blinded all Earth-based telescopes except for the Chinese GECAM-C, as it was undergoing maintenance.
