"Unveiling the Universe's Power: Highest-Energy Gamma-Ray Line Discovered!"
In an astonishing breakthrough, a team of scientists from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) has discovered the highest-energy gamma-ray line ever observed in the universe. This record-breaking discovery, measuring up to a staggering 37 million electron-volts , originated from an exceptionally bright gamma-ray burst (GRB) named GRB 221009A. Credit: Unsplash/CC0 Public Domain Gamma-ray bursts, known as the most powerful explosions in the universe, can occur during the collapse of massive stars or when neutron stars and black holes collide. GRB 221009A, observed on October 9th, 2022, belongs to the former category and has been dubbed the "brightest of all time." To capture and analyze this extraordinary event, a collaboration team, including researchers from IHEP, Yunnan Observatories, Hebei Normal University, and Guizhou Normal University, used data from two space gamma-ray monitors: GECAM-C and Fermi/GBM. While Fermi/GBM ...
