Cosmic Ray Mystery solved

Scientists Discover Source Of Cosmic Rays, ‘Incontrovertible Evidence’

New research conclusively proves that cosmic rays come from the explosion of distant exploded stars otherwise known as supernovae, say scientists.

Cosmic rays are a form of high-energy radiation made up of [mostly] ultra-fast moving protons that constantly hit earth.

The rays stream through the galaxy interacting with air molecules in Earth’s upper atmosphere creating showers of charged particles. They can have energies much higher than those produced in the Large Hadron Collider.

The mystery of where they come from has long puzzled scientists. While it was suspected that many of the cosmic rays detected at Earth were accelerated in the intense blasts from the death of big stars, the evidence was ambiguous.

Part of the reason is the protons’ positive charge when interact with the earth’s atmosphere. Because they get deflected by any magnetic field they encounter as they move through space, it made it impossible for scientists to accurately track them back to their point of origin.

Researchers’ solution was to look for a characteristic light signature it could lock onto and link to known space events.
