Gamma Burst: The most intense beam ever detected

Several astronomers and amateurs recently witnessed the strongest and brightest “Gamma” flash of light ever detected, emitted at a distance of 2.4 billion light-years from Earth. The Oukaimeden Observatory, under the Cadi Ayyad University of Marrakech, was also able to witness, through the MOSS and HAO telescopes, this phenomenal explosion thanks to the alert from NASA’s SWIFT telescope.

The burst produced a high-energy beam of radiation, up to 18 times more powerful than its previous one. This has been called the most intense ray burst of electromagnetic radiation. GRB 221009 A, as the signal is called, was first detected on Sunday October 9 even though the explosion normally occurred 1.9 billion years ago. The ray originated from the Arrow constellation and the explosion remained detectable for more than 10 hours, breaking another record.

According to different sources, scientists have estimated that the phenomenon is due to the death of giant stars, which are 30 times the size of the Sun. This is what astrophysicist Brendan O’Connor explained to AFP, adding that “the star explodes and becomes a supernova, before collapsing in on itself and forming a black hole. Matter then forms a disc around the black hole, is absorbed and released there as energy traveling at 99.99% of the speed of light.”.

On a four side, astronomer Roberta Pillera, one of the first to detect the ray said that “this burst is much closer than typical GRBs, which is exciting because it allows us to detect many details that would otherwise be too faint to see. But it’s also one of the most energetic and brightest bursts ever seen at any distance, which makes it doubly interesting.”.

Astronomers have clarified that this is indeed a rare event and seems very close, it was too far to really threaten life on Earth.
