The IceCube neutrino detector has allowed researchers to resolve a debate about what types of particles make up ...

Cosmic rays coming from ultrapowerful sources in the distant universe can pose risks to humans on Earth — particularly frequent air travelers, who are routinely exposed at the high altitudes of ...

Data from a South Pole observatory shows that the fraction of protons in ultrahigh-energy cosmic rays is lower than expected.

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 ...

Cosmic rays are high-energy charged particles, mostly protons or heavier atomic nuclei, that constantly bombard Earth from space. Scientists first detected them in the early 20th century, ...

The Alpha Magnetic Spectrometer (AMS) 02 experiment aboard the International Space Station (ISS) recently found very similar amounts of antihelium-3 and antihelium-4 in cosmic rays.

An ultra-high-energy cosmic ray carries tens of millions of times more energy than any human-made particle accelerator such as the Large Hadron Collider, the most powerful accelerator ever built ...

Cosmic rays help supernovae explosions pack a bigger punch Date: July 19, 2021 Source: Royal Astronomical Society Summary: The final stage of cataclysmic explosions of dying massive stars, called ...

Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic ...
