Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic ...

SALT LAKE CITY — The first thing to know about potential alien invaders is that the U.S. Government no longer classifies them as unidentified flying objects. That sounds too scary. They are classified ...

An illustration of a young solar system immersed in high-energy cosmic rays from a nearby supernova. Unlike considering only direct injection of supernova ejecta, this process naturally explains key ...

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 ...

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 ...
