Nearly 100 years ago, scientists detected the first signs of cosmic rays — subatomic particles (mostly protons) that zip through space at nearly the speed of light. The most energetic cosmic rays hit ...

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the ...

A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data ...

A dead star accelerates protons to extreme speeds, shedding light on the origin of the most energetic cosmic rays.

The international collaboration of the Dark Matter Particle Explorer (DAMPE) satellite on Thursday announced its latest findings, reporting for the first time the observation of the charge-dependent ...

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 ...

But if cosmic-ray immersion is sufficient—and common—then the conditions that helped shape Earth may arise around a large fraction of sun-like stars. Of course, our work does not claim that supernova ...
