Long-term study The HESS observatory in Namibia has made a “unique measurement” of the electron and positron cosmic ray spectrum. (Courtesy: Klepser/DESY/HESS collaboration/CC BY-SA 3.0) A new ...

Kinky particles: the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. The inset shows the cosmic ray proton spectrum measurement by GRAPES-3 along with observations by ...

The source of this extragalactic cosmic ray, detected on May 27, 2021, remains an enigma, as its incoming direction does not align with any known astronomical objects.

The GRAPES-3 experiment in Ooty, India discovered a kink in the cosmic-ray proton spectrum at around 166 tera-electron-volt (TeV). The new feature will advance our understanding of the cosmic ray ...

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 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 ...

Past observations revealed the cosmic ray energy spectrum is made up of several peta-electron volts, suggesting the Milky Way itself accelerates particles up to that limit. However, the origin of ...

Cosmic rays are made of subatomic particles, such as protons and electrons, whose energies span a wide spectrum. Ultra-high-energy cosmic rays easily host tens of millions of times more energy ...

Researchers at the Large High Altitude Air Shower Observatory (LHAASO) have accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 ...

In 2021, scientists picked up the new cosmic ray, named Amaterasu, when it triggered 23 of those detectors. The array showed that it was coming from the Local Void, an empty part of space on the ...
