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...

The biggest explosion ever in the cosmos captured by NASA; It BIRTHED a black hole?

[ad_1] NASA captured a wave of radiation hitting Earth that came from the biggest explosion ever recorded in history. Astronomers believe it could be from the explosion of a supernova that actually birthed a black hole. Last year, NASA captured something stunning that strangely went under the radar. A gigantic cosmic explosion was captured by the NASA Fermi Gamma-ray Space Telescope as well as a few other observatories, which is now being dubbed as the biggest and the brightest explosion in recorded history. As studies are ongoing to gain a better understanding of the event, an early belief is that the energy came from a supernova explosion 1.9 billion light years away, the death of a massive star, and it indicated the birth of a black hole.NASA posted on its blog post, revealing deta...

Chinese scientists detect brightest gamma-ray burst to date: Report

[ad_1] Chinese scientists have detected the brightest gamma-ray burst to date through combined observations from both Earth and space. Chinese scientists have detected the brightest gamma-ray burst (GRB) to date through combined observations from both Earth and space, according to the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences. The combined observations were made on October 9, 2022, by China's Large High Altitude Air Shower Observatory (LHAASO), the High Energy Burst Searcher (HEBS) -- an all-sky monitor for gamma-ray transients -- as well as China's X-ray astronomy satellite Insight-HXMT (Hard X-ray Modulation Telescope), achieving multi-spectral measurements of the gamma-ray burst, coded as GRB 221009A. GRBs are immensely energetic explosions tha...

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...
