It's 1961, and four intrepid cosmic explorers journey to space under the leadership of Reed Richards, where they encounter cosmic rays that change them forever. But what are cosmic rays?

Pasko explains, In our modeling, the high-energy X-rays from relativistic electron avalanches create new seed electrons due to the photoelectric effect in air, which quickly grow these avalanches.

So gamma rays emanating from SNR’s come from speeding protons. Cosmic rays are made of speeding protons. Case closed — or almost, anyway. It’s still circumstantial. “There are other ...

Cosmic rays may play a role in triggering lightning, a new study suggests, offering an out-of-this-world answer to a long-standing mystery.

Cosmic rays, which are found throughout space, could make even the darkest, coldest corners of our solar system viable for life. Enjoyed this article?

When we think about how radiation effects life, we usually have a negative picture in our head, but on Mars, radiation could be sustaining life.

But cosmic rays are known to lose energy rapidly the more time they spend in magnetic fields because of the synchrotron radiation they emit while in the fields.

Mars, Europa and Enceladus are the three most promising locations in the solar system to search for life living off cosmic ...

New research published by Michigan State University astrophysicists could help scientists answer a century-old question: where did galactic cosmic rays come from?  ...
