In principle, cosmic-ray observations can provide detailed insights into the physical profile of a passing ICME. But despite ...

The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles. The CALorimetric Electron ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

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 ...

Many massive stars explode as supernovae. If cosmic-ray baths are common in such environments, then the thermal histories that shaped Earth's interior may be common as well. This realization has ...

For decades, astronomers were certain that half of the ordinary matter in the universe — protons and neutrons, the building blocks of everything we see — had simply gone unaccounted for. The cosmic ...

Artist’s illustration of the extremely energetic cosmic ray observed by a surface detector array of the Telescope Array experiment, named “Amaterasu particle.” In 1991, the University of Utah Fly’s ...

China’s Large High Altitude Air Shower Observatory (LHAASO)–one of the country’s key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic ...

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 ...

Astronomers have detected a mysterious gamma-ray glow from the Milky Way’s halo, potentially marking the first direct observation of dark matter. In a study published November 25, 2025, in the Journal ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Much of our understanding of the Universe and its mysterious phenomena is based on theoretical interpretations. In order to deepen the understanding of distant objects and energetic phenomena, ...
