The most powerful cosmic ray, named the Oh-My-God particle, was detected more than 30 years ago and measured around 320 exa-electron volts (EeV) when it was discovered.

The cosmic ray’s arrival path, situated near the Milky Way’s disk, suggests that it likely experienced only minor deviations when zipping through magnetic fields (which are ubiquitous ...

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 ...

Muons can also be formed in cosmic-ray spallation, wherein a cosmic ray enters Earth's atmosphere and collides with a molecule or atom, smashing it apart into a shower of subatomic particles ...

The abundances of heavy nuclei in the low energy primary cosmic ray flux can be accounted for by the co-existence of two components, one of which has undergone nuclear spallation reactions. The ...

Numerical simulations by a small international team of physicists may yet save the supernova theory of cosmic ray em. advertisement. The Universe's Most Powerful Cosmic Rays May Finally Be Explained.

If the cosmic ray was a single proton, then it seems to have come from an area called the Local Void, which is exactly what it sounds like. But if it was the stripped-bare nucleus of a carbon, ...

Two isotopes of phosphorus due to spallation of atmospheric argon have also been found2. We can now add to the list sulphur-35. Nature - Radioactive Sulphur produced by Cosmic Rays in Rain Water ...

Earth has been blasted by the second strongest ultrahigh-energy cosmic ray ever observed. While its origins remain unknown, astrophysicists are pointing the finger at the Local Void, a ...

The origin of lithium (Li), the third element of the periodic table, has long been shrouded in mystery. This element, commonly found in cosmic rays as two stable isotopes, 6Li and 7Li, is crucial ...

An underlying mechanism might be responsible. Earth seems to shake more after intense cosmic radiation hits its surface, a new study suggests. The surprising study by a team of Polish researchers ...
