Shocking Gamma-Ray Burst shatters record; is brightest in 10000 years; beats Sun, says NASA

[ad_1] In October last year, astronomers detected the 'most-powerful ever' gamma-ray burst shockingly close to Earth. According to NASA, a gamma-ray burst (GRB) is a short-lived burst of gamma-ray light, which is the most energetic form of light. Although these bursts are short-lived, they shine a million trillion times as bright as the Sun. The gamma-ray burst observed on October 9 was so powerful that scientists initially thought it came from a source not too distant from Earth, and it lit up gamma-ray detectors on telescopes around the world.Instead, it was a terrifyingly powerful explosion of gamma-rays from a source further away than they had previously assumed and was renamed GRB221009A. Now, researchers have finally combed through all the data and have revealed that it was the br...

Mysterious Gamma-ray burst baffles scientists, causes NASA rethink on how black holes are formed

[ad_1] A recent NASA study could change the understanding of gamma-ray bursts and black hole formation. Know all about it here. Almost a year ago on December 11, Earth was witness to a high energy gamma-ray burst (GRB) which was suspected to be emitted from the outskirts of a galaxy around 1 billion light-years away. What made this cosmic burst unusual was the fact that it did not submit to any one pre-defined category of gamma-ray bursts. It left scientists baffled and put a doubt into their previous understanding of GRBs.According to NASA, GRBs are classified into two categories – long bursts and short bursts. Long bursts which emit gamma rays for two seconds or more and originate from the formation of dense objects like black holes in the centers of massive collapsing stars. Short ...

Astonishing! Most-powerful ever gamma-ray burst ever detected shockingly close to Earth

[ad_1] Gamma-ray burst detected by astronomers was the nearest ever burst to Earth. It was million trillion times as bright as the Sun. In an astonishing development, astronomers have detected the ‘most-powerful ever' gamma-ray burst shockingly close to Earth. The burst was first detected by telescopes on October 9. According to NASA, a gamma-ray burst (GRB) is a short-lived burst of gamma-ray light, which is the most energetic form of light. Although these bursts are short-lived, they shine a million trillion times as bright as the Sun. Any closer and it would have been catastrophic.The gamma-ray burst observed on October 9 was so powerful that scientists initially thought it came from a source not too distant from Earth, according to ScienceAlert. Astronomers initially confused it w...
