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 ...

That there are “hot spots” of cosmic rays in the sky. Large-scale surveys of cosmic rays suggest that there are a few hot spots in the sky that seem to produce more cosmic rays than others, but we don ...

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

Cosmic ray found decades ago had 'more energy than was theoretically possible' The most powerful cosmic ray, named the Oh-My-God particle, was detected more than 30 years ago and measured around ...

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

Cosmic rays constantly rain down on Earth but nobody knows exactly where they come from. (Image credit: DrPixel via Getty Images) The crux of the cosmic-ray mystery is how these particles can ...

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 ...

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.

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?

Scientists from the ScanPyramids project use cosmic-ray muon radiography equipment to view a corridor hidden inside the Great Pyramid of Giza, constructed some 4,500 years ago for ancient Egypt's ...
