The stars core ran out of fuel and collapsed into a black hole. Some of the matter swirling toward the black hole was redirected into dual jets firing in opposite directions.

Utilizing data from NASAs Fermi Gamma-ray Space Telescope, researchers discovered a unique energy peak in the aftermath of the brightest Gamma-Ray burst ever seen, suggesting the annihilation of electrons and positrons. This finding provides new insights into the behavior of cosmic jets and the extreme conditions following such bursts.
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASAs Fermi Gamma-ray Space Telescope reveals a feature never seen before.
Unprecedented Spectral Feature Identified
A few minutes after the BOAT erupted, Fermis Gamma-ray Burst Monitor recorded an unusual energy peak that caught our attention, said lead researcher Maria Edvige Ravasio at Radboud University in Nijmegen, Netherlands, and affiliated with Brera Observatory, part of INAF (the Italian National Institute of Astrophysics) in Merate, Italy. When I first saw that signal, it gave me goosebumps. Our analysis since then shows it to be the first high-confidence emission line ever seen in 50 years of studying GRBs.

The accompanying video gives a great explanation of what the scientists think is happening in this extraordinary event. The gamma rays are traveling at 99.9% the speed of light.

(170 posts)1. That is a cool read
Can particles emerging from the opposing particle jets ever be considered entangled?

The article states that the colliding electrons and positrons are traveling at 99.9% of c in our direction.
