Cosmic rays hit about three times harder just beyond the heliopause — the boundary where the solar wind gives out and the ...

Every second, particles zip through your body at nearly the speed of light. They rain down from a storm high in the sky, ...

Physicists at CERN have directly measured proton-oxygen collisions at 9. 62 TeV per nucleon pair, closely recreating an ...

Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation ...

“Cosmic-ray air showers are sprays of particles raining down from high in the sky,” explains Jesse Liu of New York University, the lead author of a paper that describes the study. He adds that cosmic ...

Radiation at commercial-aircraft altitude can rise by roughly 40% to 60% when the Sun is less active, according to a new analysis of high-altitude balloon measurements. The research team reported that ...

BEIJING, Sept. 21 (Xinhua) -- By combining data from a satellite and a ground-based observatory, Chinese scientists have discovered an X-ray trail stretching 42 light-years across the cosmos. This ...

What if the amount of radiation you encounter on a flight depends not just on how high you fly, but on what the Sun is doing?

Launched in January 2024, the Einstein Probe is a space-based X-ray observatory designed to detect and study powerful, ...

Cosmic rays travel continuously through the universe until they reach Earth. Every ray that passes through our planet, completely naturally, at a rate of around 5.15 x 1018 cosmic rays ...

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 ...

An open-source Raspberry Pi Pico detector counts muons from cosmic rays for under $100, bringing particle physics to the desktop.
