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 ...

(Reuters) - Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking ...

Supermassive black holes are some of the most powerful engines in the universe. These giants sit at the centers of galaxies, including your own Milky Way, and sometimes become active by pulling in ...

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 ...

Scientists have just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world. This exceptional discovery opens up new perspectives for understanding ...

Scientists using the Milagro Gamma-ray Observatory in New Mexico have captured evidence of radiation emitted from the plane of our home galaxy at extremely high energies. The researchers detected “TeV ...

High energy astrophysics probes the most energetic phenomena in the Universe, from explosive supernova remnants to the powerful outflows near compact objects. A central focus of this field is the ...
