Cosmic ray - Wikipedia
网页Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, [1] and from distant galaxies. [2] .

网页2024年9月7日 · Cosmic ray, a high-speed particle—either an atomic nucleus or an electron—that travels through space. Most of these particles come from sources within the Milky Way Galaxy and are known as galactic cosmic rays (GCRs). The rest of the cosmic rays originate either from the Sun or, almost certainly in.

网页2023年12月5日 · Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of light, but when they hit the Earth they are generally blocked by our atmosphere and made harmless to humans.
