Gamma rays burst GRB 221009A detected by scientists is the brightest and 1 in a 10,000-year phenomenon.
It gives astronomers the chance to study this astronomical phenomenon.
GRB 221009A’s signal was traveling at the speed of 1.9 billion years before we could see it from the earth. GRB 221009A lasted around whopping 10 hours.
Astronomers Observing the ‘Gamma Rays Burst’ GRB 221009A
Astronomers are excited to observe this rarest phenomenon in real-time and they want to study the detail of what’s happening before, during, and after the death of the star.
Astronomers think that star death creates a black hole and it ingests the surrounding matter, the black holes blast out jets in opposite directions containing particles accelerated to near the speed of light.
Oxford and Sydney University researchers said – “This is the implosion that occurs simultaneously as the explosion. They could map this reverse shock in ‘unprecedented detail’ for variables such as time, length, size, and energy.”
Our observations provide unmatched insights into the reverse shock model for gamma-ray burst emission, showing it is very difficult for existing models to replicate the slow evolution of the energy peaks that we observed.”
“This means we have to refine and develop new theoretical models to understand these most extreme gamma rays burst in the Universe,” said the University of Sydney Professor James Leung.
Where is the Supernova?
NASA researchers looking at the supernova incident in this Gamma Rays Burst GRB 221009A.
They conclude that due to the gamma rays burst, GRB 221009A burst happened, the area is covered by dust and obscures the view of any light from a supernova.
Professor of Astrophysics at Radboud University in Nijmegen “If it’s there, it’s very faint. We plan to keep looking, but it’s possible the entire star collapsed straight into the black hole instead of exploding.
We cannot say conclusively that there is a supernova, which is surprising given the burst’s brightness.”
Astronomers are using James Webb Space Telescope and Hubble telescope to search for the supernova.
