In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...

Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles ...

Illustration of an array of ground-based detectors to characterize a cosmic ray shower. When high-energy cosmic particles strike the atmosphere, they produce a cascade of particles. By building a ...

This may seem like the cry of a panicking news reporter in a lurid sci-fi tale, but it’s actually a scientific fact — albeit a slightly hyperbolic one. Mysterious cosmic rays traveling at speeds ...

Discovered in 1912, cosmic rays have been studied extensively and our current understanding of them is compiled into what is called the Standard Model. Recently, this understanding has been challenged ...

The highest-energy cosmic rays come from subatomic interactions within star clusters, not supernovae, say Michigan Tech physicists and collaborators. For decades, researchers assumed the cosmic rays ...

Cosmic rays. Artwork of high-energy particles and radiation from a star in deep space (cosmic rays) impacting molecules and atoms in the Earths atmosphere. These primary impacts cause a secondary ...
