Cosmic rays are atom fragments that rain down on the Earth from outside of the solar system. They blaze at nearly the speed of light and have been blamed for electronic problems in satellites and ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

The study suggests that some recent observations of "antinuclei" in cosmic rays are consistent with the existence of WIMPs, but also that these particles may be even stranger than previously thought.

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

X-ray image of the newly discovered pulsar wind nebular associated with an extreme Galactic cosmic ray source 1LHAASO J0343+5254u, obtained by the XMM-Newton space telescope (DiKerby, Zhang, et al ...

There's too much antimatter in cosmic rays, showers of charged particles that pelt Earth. Could this be explained by annihilating dark matter? If so, does it point to the existence of WIMPs?

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.

GUIDE: Of the nine cosmic ray stations built across Canada, the Sulphur Mountain location became the most important due to ...
