How do gamma ray bursts happen
Gamma-ray bursts are very bright as observed from Earth despite their typically immense distances. An average long GRB has a bolometric flux comparable to a bright star of our galaxy despite a distance of billions of light years (compared to a few tens of light years for most visible stars). Most of this energy is released in gamma rays, although some GRBs have extremely luminous optica… Web1 day ago · GRB221009A, was spotted on 9 October. This type of gamma ray burst (GRB) is thought to occur when a massive star explodes in a supernova, leaving behind a black hole. It is about 2.4 billion light years away and is being called “the BOAT” – the brightest of all time. 14 Apr 2024 03:37:41
