Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

This progress means that, for the first time, complicated astrophysical events like shocks and turbulence can be studied in a ...

Cosmic rays—high-energy particles moving close to the speed of light—originated from somewhere in the Milky Way galaxy and beyond, but exactly where has been a mystery since they were ...

Scientists have observed the mechanism responsible for generating cosmic rays in a laboratory for the first time – a significant milestone in astrophysics.

Cosmic rays are high-energy charged particles, mostly protons or heavier atomic nuclei, that constantly bombard Earth from space. Scientists first detected them in the early 20th century, ...

Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

There's too much antimatter in cosmic rays, showers of charged particles that pelt Earth. Could this be explained by annihilating dark matter? If so, does it point to the existence of WIMPs?

Cosmic rays may offer an out-of-this-world answer to a long-standing mystery about lightning on Earth, a new study suggests. Thunderstorms are exceedingly common; a staggering 3 million lightning ...
