The most mysterious of these are ultra-high-energy cosmic rays (UHECRs), which exceed 10¹⁸ electron volts (eV) in energy.

James (Jim) Cronin also devoted the second half of his career to studying cosmic rays. He conducted an experiment known as the Chicago Air Shower Array (CASA), which ran from 1992-1999 in Utah to ...

A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino using the KM3NeT telescope, with an energy level 16,000 times greater than ...

Although scientists have known about Ultra-High Energy Cosmic Rays (UHECRs) for years, nobody can pinpoint their origin. When these UHECRs hit the ground, however, they cause a widespread local ...

A radical new study suggests that ultra-high-energy cosmic rays may not come from distant black holes or supernovas—but from dark matter particles annihilating in our galaxy. A Russian ...

Artist’s illustration of ultra-high-energy cosmic ray astronomy to clarify extremely energetic phenomena in contrast to a weaker cosmic ray that is impacted by electromagnetic fields.

Cosmic rays are protons or atomic nuclei that travel ... BIMAP-3D "provides an unprecedented capability in high-resolution, 3D lightning source mapping and source polarization detection for ...
