A record-breaking gamma-ray burst detected in October 2022 has now been described as a one-in-a-thousand years event.
It’s called GRB 221009A, and with up to 18 teraelectronvolts of energy packed in its emissions of light, it’s considered the most powerful gamma-ray burst on record.
We’ve been waiting to learn more about this incredible explosion, and now the analyses have started to arrive on preprint server arXiv, with a trio of papers submitted to The Astrophysical Journal Letters.
