Gamma-ray burst from distant supernova creates unprecedented ionospheric disturbance on earth

A gamma-ray burst (GRB) called GRB 221009A, originating from a supernova explosion, has impacted Earth's ionosphere. This event challenges the assumption that GRBs cannot affect the ionosphere. Data from the China Seismo-Electromagnetic Satellite (CSES) revealed disturbances in the upper ionosphere caused by the GRB. Scientists are now exploring effects of other GRBs on Earth's ionosphere using ground-based and space-based detectors. This discovery also raises concerns about supernova explosion
