Gamma-ray bursts were once a mystery that astronomers were gloomy about solving. There is now an accepted theory that gamma-ray bursts are energy flowing from stars that explode as supernovae. Or from the collision of two dense neutron stars, whose gamma-ray bursts have been measured since the 1960s.
recently International team of astronomers Together with the National Institute for Astrophysics in Rome, Italy, they released their investigation of a massive gamma-ray burst hitting Earth, called GRB 221009A, on Oct. 9, 2022, which was detected by several satellites orbiting nearby. word and the Integral Space Telescope which is the International Gamma Ray Astrophysics Laboratory of the European Space Agency The explosion created massive turbulence in Earth’s outer atmosphere for about 13 minutes. Astronomers described it as the most powerful explosion ever seen. Along with explaining the origin, about 2,000 million years ago, in a galaxy far from our Milky Way galaxy. A large star faced disaster and ended its life by exploding as a supernova. and emits enormous gamma rays. those rays Traveled across the universe and arrived on Earth last year.
Newly released studies indicate that these gamma-ray bursts cause large variations in the electric field of Earth’s ionosphere. which is the upper atmosphere layer Located some 50 to 950 kilometers from Earth’s surface, it is home to an ionized gas called plasma. Instruments on Earth show that gamma rays disrupt the ionosphere for several hours. It also damaged lightning detectors in India.
