GRB 221009A, a gamma-ray burst
GRB 221009A, a gamma-ray burst detected on October 9, 2022.
Astronomers think GRB 221009A represents the collapse of a star many times the mass of our Sun.
It signals the birth of a new black hole, formed at the core of a collapsing star long ago in the distant universe.
An emerging black hole drives powerful jets of particles traveling near the speed of light. The jets pierce through the star, emitting X-rays and gamma rays as they stream into space.
One of the brightest gamma-ray bursts ever detected GRB 221009A is also close as far as gamma-ray bursts go but still lies about 2 billion light-years away.
Fermi Gamma-Ray Space Telescope captured the data at gamma-ray energies, detecting photons with over 100 million electron volts. In comparison, visible light photons have energies of about 2 electron volts.
