When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them ...

A cosmic-ray detector built at CERN has measured muons from one pole to the other. The Courier spoke to James Devine and Etam ...

Scientists have identified an accelerator that produces the highest-energy protons in our galaxy, a finding that could ...

An accelerator of the highest-energy protons in our galaxy has been identified; it could help scientists better understand ...

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 high-speed particles created by supernova explosions and other space interactions, carrying elements that can ...

Ultraheavy particle clue: Penn State-led research suggests some ultrahigh-energy cosmic rays are made of nuclei heavier than iron, altering theories on their origins. Record-breaking events: The 2021 ...

Our planet has recently been struck by an extraordinary burst of cosmic rays, demonstrating an intensity level that is unparalleled in recorded history. As we delve into the specifics of this event, ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...
