Italian scientists discover that gamma-ray burst GRB 221009A impacted Earth's upper ionosphere, an unusual occurrence. The China Seismo Electromagnetic Satellite (CSES) recorded a significant spike in the electric field in the top-side ionosphere, shedding light on the connection between gamma-ray bursts and the ionosphere. Analysis is ongoing to determine if gamma-ray bursts have the potential to disturb Earth's ozone layer. #science #cses #space
