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 most powerful cosmic rays in the universe currently have no explanation. New research suggests that exotic, ...

For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light, packing ...

Especially the latter poses a great challenge for long-term space travel, and so people are working on various concepts to protect astronauts’ DNA from being smashed by cosmic rays. This has ...

THE purpose of this communication is to point out the existence of a large tropospheric and stratospheric effect produced by the solar-cycle modulation of cosmic rays. Since there is some evidence ...

Opinion High energy neutrinos are the coolest particles in astrophysics. Born in distant cosmic cataclysms, they speed ...

About 2.5 million years ago, the viruses infecting fish in Lake Tanganyika underwent a mysterious explosion in diversity. It may have been a nearby star exploding.

AMS measurements provide insights i... Cosmic rays and their byproduct, muons, may help scientists study tornado formation by detecting pressure changes remotely. This technique would avoid the ...

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right ...

Tomography is the term used to describe a technique of viewing a cross-section of a solid object using x-rays or an ultrasound. A muon is a particle that is 200 times heavier than an electron. The ...

DURING the last ascent of the balloon F.NM.S. (August 18, 1934), we had the opportunity of measuring with precision the intensity of cosmic rays at altitudes of about 12,000 m., 15,000 m.

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." Using 16 years of data ...
