Pierre Auger Observatory scientists used cosmic-ray muon fluctuations to set the tightest-ever limit on hadronic Lorentz ...

In 2022, researchers detected a very odd photon from an enormous gamma ray burst that should have been destroyed on its way ...

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 ...

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 ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

Cosmic rays are relativistic charged particles that pervade the Galaxy and beyond, carrying crucial information about violent astrophysical processes and influencing the dynamics of interstellar and ...

A new observatory is set to detect sources of cosmic rays, dark matter and other relics of the Big Bang in a few years' time.

The failure of ghostly subatomic messengers called neutrinos to show up at an Antarctic telescope has knocked down a major astrophysical theory involving some of the most dramatic explosions in the ...

The Airbus A320 was forced to make an emergency landing and 15 people were hospitalized after it plummeted thousands of feet. Reporter A JetBlue plane that suddenly plummeted thousands of feet in ...
