NASA scientists discovered lthe brightest gamma-ray burst on record. According to experts, this GRB (Gamma Ray Burst, that is, Gamma Ray Burst in English) It was 10 times brighter than any previously detected.
to show pictures a phenomenon that occurs 2,000 million light years from EarthIt illuminated much of our galaxy and His rainbow is like a target shooting a target.
The team that detected the burst used a satellite telescope designed to study GRBs from space at its Neil Gehrels Observatory. At first they could not detect it because our planet blocked the view, however, after 55 minutes, when the orbit of the satellites allowed them to see the GRB, its systems were successfully detected and its images were captured.
He was publicly named GRB 221009Aand those who work in the Nisa Swift team, called it NAVIS (the English initials “the most famous of all times”, that is “the most famous of all ages”).
“We are very lucky to see something like this. We estimate that such bright events occur about once every thousand years.”said Phil Evans, an X-ray astronomer who was involved in the work.
“The study of this evolution is amazingly bright GRB abundantly; we can learn a lot about the physics of shock waves“, he added.
“As slow-motion images show details of movements, breaking down our data into smaller objects allows us to see how GRBs change and learn more about them,” he said.
What are gamma ray bursts?
Gamma-ray bursts are the most violent explosions in the Universe, which more than the sun to release 10 billion energy in years.
The results are catastrophic supernova explosions as massive stars die.. Studies indicate that it happens when black holes are formed by a powerful type of supernova.
First, this hole creates a magnetic field that breaks the energy of the emission. Then, when this magnetic field decreases, this material breaks and dominates.
Previously, it was thought that force was controlled by one of the two, but recent studies have shown that both the magnetic field and energy play a fundamental role.
The first GRB was detected by a satellite in the late 1960s to reveal violations of the Soviet Union’s nuclear ban treaty efforts. Since then they have been seen by thousands on different media.
