Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

Many massive stars explode as supernovae. If cosmic-ray baths are common in such environments, then the thermal histories that shaped Earth's interior may be common as well. This realization has ...

Earth is under constant bombardment by cosmic rays, showers of high-energy particles that blast our planet from all directions at near light speed. While this might sound like the precursor to a ...

A navigation system based on high-energy particles created by cosmic rays has been successfully tested underground for the first time. The technology could one day be used to guide underground and ...

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from. When you ...

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 ...
