Cosmic X-ray flashes are a phenomenon when the night sky seems calm to the naked eye but in the electromagnetic spectrum. The ...

A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth.

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 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 ...

A study published in Physical Review Letters by a research team at Penn State University offers a potential explanation. Led ...

Scientists still don’t know where ghostly particles called neutrinos originate. A distant galaxy could be a potential source.

The reason photographic darkrooms are needed is because almost any amount of light can ruin the film or the photographic paper before they are fixed. Until then these things are generally kept in ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...

Imagine being able to see through walls of steel and concrete without cutting, drilling, or opening a single door. For decades, this has been the dream of scientists and security experts tasked with ...
