A new experiment set for an Aug. 14 launch to the International Space Station will provide an unprecedented look at a rain of particles from deep space, called cosmic rays, that constantly showers our ...

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It ...

The GRAPES-3 experiment in Ooty, India, operated by the Tata Institute of Fundamental Research has discovered a new feature in the cosmic-ray proton spectrum at around 166 tera-electron-volt (TeV) ...

A view of the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. Results of cosmic ray proton spectrum measurement by GRAPES-3 along with space and ground-based ...

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

An incredibly fast-moving particle from space recently arrived on Earth, and physicists are rushing to figure out what it is and where it came from. Called the Amaterasu particle, after the Shinto ...

The Large Hadron Collider (LHC) and its associated experiments undergo an annual, multi-week reset and calibration procedure following a winter hibernation period, essential for accurate data ...
