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

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

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

A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

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 ...

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 ...

The rays — which consist of electrons and their antimatter counterparts, positrons — were observed at energies all the way up to 40 teraelectronvolts (TeV), or 40,000 times the energy of ...
