Long-Duration Gamma-Ray Burst Traced to Nucleus of Ancient Galaxy
Unlike most gamma-ray bursts, which are caused by exploding massive stars or the chance mergers of neutron stars, a long gamma-ray burst event dubbed GRB 191019A came from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy, suggests an analysis of

In October 2022, spacecraft and sensors worldwide picked up what scientists are now calling the brightest gamma-ray burst ever detected. It was so bright and intense that the burst created a particle that shouldn’t exist. Further, NASA
Brightest gamma-ray burst ever reveals new mysteries of cosmic explosions
In 2022 on October 8, an intense pulse of gamma-ray radiation swept through our solar system. The source, dubbed GRB 221009A for its discovery date, turned out to be the brightest gamma-ray burst (GRB) ever recorded. GRB 221009A lasted over 300 seconds. According to astronomers, such “long-duration” GRBs are the birth cry of a black
Record-breaking gamma-ray burst possibly most powerful explosion ever recorded
Thanks to a fast reaction by observers and staff, near-simultaneous observations were made of GRB221009A from Gemini South in Chile. The image is a combination of 4 exposures in I, J,H, K with two instruments taken in the morning of Friday 14 October 2022. Credit: International Gemini Observatory/NOIRLab/NSF/AURA/B.
