Cosmic rays are actually particles from space that travel across the universe. They started out as atoms that had their outer layers stripped away and are now just nuclei. They move extremely ...

Now, researchers led by Los Alamos National Laboratory have proposed a bold new idea: that stars collapsing into black holes ...

Cosmic particles with phenomenal energy have puzzled scientists for decades. A new theory may finally unveil their origin.

The cosmic rays that rain down on Earth are predominantly protons (~90%), helium nuclei (~9%), and electrons ... Materials with low atomic number provide the most effective protection against ...

They are birthed from collisions between high-energy protons and atomic nuclei that make up cosmic rays, and molecules in Earth’s atmosphere. They exist for only about 2 microseconds before ...

These are cascades of subatomic particles and ionized nuclei produced in the Earth's atmosphere by high-energy particles ("cosmic rays") from both our sun and violent events like supernova ...

The radiation we receive from outer space is called cosmic radiation or cosmic rays. We also receive exposure from man ... Some natural elements are unstable. Therefore, their nuclei disintegrate or ...

That "something else" appears to originate from space. Cosmic rays are protons or atomic nuclei that travel through space at nearly the speed of light. They are produced by our Sun, other stars in ...
