Gamma ray :
Space is an unending vastness of astounding phenomena.
Scientists recently detected one of the most powerful occurrences in the cosmos, extremely powerful light bursts also known as the Gamma ray burst.
These gamma ray bursts were detected by the Large High Altitude Air Shower Observatory (LHAASO), located on Haizi Mountain, Sichuan, China, and the observation was published in Nature. According to the published report, these light bursts occurred with extremely high energy levels than ever before.

The Large High Altitude Air Shower Observatory (LHAASO) detected more than 529 gamma ray explosions with energy levels crossing 0.1 quadrillion electron volts. And of those bursts, one of the gamma rays observed with the energy level of up to 1.4 quadrillion electron volts is said to be one of the highest energy gamma radiation burst ever to be recorded in the detailed observation history.
To get an idea of how powerful the burst was, the protons in the Large Hadron Collider, the largest and most powerful particle accelerator in the world could reach energy levels close to a few trillions of electron volts.

Stunning Cosmic Fact: In January 2019, NASA’s Hubble Space Telescope detected the most energetic explosion ever observed in the Universe, the outburst’s energy released for a few seconds was more than the total energy that can be produced by the Sun in its complete 10-billion year lifespan. This ultrahigh-energy gamma burst was detected in the middle of a galaxy situated 5 billion light-years away.
In the observation, the researchers spotted 12 hot spots of the gamma burst, proving that our galaxy- The Milky Way houses the most powerful cosmic particle accelerators.
For these gamma rays to attain such immense energies the acting natural magnetic fields must accelerate the charged particles like protons and electrons close to the speed of light in order to produce such massive and powerful bursts.
But the researchers haven’t fully understood what kind of environments could propel the light-bursts with such unfathomable energy levels.
However, the scientists have brought out 2 possibilities. One is the crab Nebula, the unstable and violent debris of an exploded star, and the other is the Cygnus Cocoon, a belt where massive stars take birth.
The researchers stated that further detailed studies are needed to better understand these ultrahigh-energy gamma ray bursts.
