Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

But occasionally cosmic rays have much higher energy than usual. We've known about this since 1962, but we still have no idea why. We also don't know where this ultra-high-energy cosmic radiation ...

An ultra-high-energy cosmic ray carries tens of millions of times more energy than any human-made particle accelerator such as the Large Hadron Collider, the most powerful accelerator ever built ...

Historically, other high-energy cosmic rays have been detected, such as a 320-EeV particle in 1991, a 213-EeV particle in 1993, and a 280-EeV particle in 2001, all in the Northern Hemisphere.

This energy level matches the most energetic cosmic ray ever observed, nicknamed the “Oh-My-God particle”, which was estimated to have an energy of 320 EeV when detected in 1991. From many candidates, ...

LHAASO has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, ... These high-energy cosmic rays collide with interstellar gas and produce gamma rays.

A cosmic-ray particle with an energy about 36 million times greater than the particles accelerated by CERN’s Large Hadron Collider has been detected. At 244 EeV, this is one of the most energetic ...

Cosmic rays are made of subatomic particles, such as protons and electrons, whose energies span a wide spectrum. Ultra-high-energy cosmic rays easily host tens of millions of times more energy ...

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from.
