In October 2022, scientists detected the explosive death of a star 2.4 billion light-years away that was brighter than any ever recorded.
The signal could help explain why an explosion called a gamma ray burst appeared to be the most powerful ever detected.
When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Follow-up studies showed that GRB 221009A was 70 times brighter and far more energetic than the previous record holder.
