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 ...

Georgia State Regents’ Professor of Physics and Astronomy Xiaochun He and his students have developed a detector to measure cosmic rays and investigate how space weather can impact our changing ...

Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...

Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 exa-electronvolts. Its apparent arrival from a nearly empty region of space ...

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right lighting ...

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

The investigation of cosmic rays and their potential connection with dark matter occupies a central role in contemporary astrophysics. Recent experimental and theoretical advances have refined our ...

The sprawling Auger Cosmic Ray Observatory in South America has produced its first major discovery while still under construction. The international Auger collaboration has traced the rain of ...

These cosmic rays typically come from the extremely distant universe, from ultrapowerful events such as supernovas and quasars. When you purchase through links on our site, we may earn an affiliate ...
