For the first time, an international collaboration of more than 800 scientists has joined forces to track down the sources of high-energy cosmic neutrinos. By combining neutrino observations ...

For decades, a sharp kink in the energy spectrum of particles raining down from space has taunted astrophysicists, hinting at powerful engines in our Galaxy but refusing to reveal their identity. Now ...

Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the most energetic ever detected. The event drew international attention 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 ...

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 are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in ...

From 19 to 22 January, 80 particle physicists, astronomers and cosmologists gathered at CERN for the first “All that ...
