Cosmic ray air showers are produced when high-energy cosmic particles enter Earth’s atmosphere and interact with atmospheric nuclei, generating cascades of secondary particles. These extensive air ...
Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the ...

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 ...
Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

One of the most powerful cosmic rays ever detected may have come from this nearby starburst galaxy
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 ...
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 ...
Astronomers have detected the radio afterglow of a powerful space explosion that went unseen, possibly an orphan gamma-ray burst or a rare blackhole event 1.7 billion light-years away ...
The Universe is a very violent place, and one truly gets a sense of that when looking at short gamma-ray bursts (GRB). That would be intense and brief explosions in space that last just about two ...
An artistic illustration of the magnetar and the gamma-ray burst jet in this work (Illustration: Yuja Tian and Yuting Wu, Nanjing Zhijiao Cloud Intelligent Technology Co., Ltd.; Scientific concept ...
