An enormous gamma-ray burst from a dying star was the most powerful recorded, scientists have said.

The October 9 gamma-ray burst was thought to be from a dying star collapsing into a black hole."GRB221009A was between 10-100 times brighter than other gamma-ray bursts, making this a once-in-a-century explosion. The GRB [gamma-ray burst] afterglow is booming bright at all wavelengths, including optical and infrared., which makes GRB221009A one of the closest very energetic GRBs to date," O'Connor added.
After the gamma-ray burst was detected by satellites, Andrew Klekociuk, an atmospheric scientist at the Antarctic Climate Program, used an Earth probe antenna to measure its effects. His data found that the waveforms of the gamma-ray burst and the increase in electrical current in the Earth's surface matched nearly identically.
