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 ...

The study, authored by a Russian astrophysicist and published in a preprint on arXiv, suggests that these extreme cosmic rays ...

Earth’s magnetic field acts as a protective barrier against the majority of these cosmic rays, and there is a measurable increase in radiation as you gain altitude and enter space. In space ...

We still don't fully understand what triggers lightning. A new study suggests that showers of cosmic rays may be the missing link.

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 the ...

Gamma-ray bursts, the most powerful kinds of explosions known in the cosmos, may help provide a piece of the puzzle when it ...

In a new study, researchers from the Los Alamos National Laboratory in New Mexico argue that this spark is often provided by cosmic ray showers. These are cascades of subatomic particles and ...

The research team found that cosmic ray showers, particles from outer space, play a pivotal role in creating the paths which ignite lightning flashes within thunderstorms. Cosmic rays travel ...
