Gamma Ray Burst: GRB
Astronomers have recently observed the brightest flash of light ever observed.
This glow is caused by a phenomenon that occurred at a distance of 2.4 billion light years from Earth. This phenomenon is a gamma ray burst or burst. It is named GRB221009A.
This type of GRB occurs when a massive star explodes in a supernova. This leads to the formation of a black hole in most cases. GRBs are the most powerful explosions observed in the universe since the Big Bang.
They are brief, but intense flashes of gamma radiation. These explosions generate as much energy as the Sun will emit during its entire 10 billion year existence.
