Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 exa-electronvolts. Its apparent arrival from a nearly empty region of space ...

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

Earlier this year, an underwater detector in the Mediterranean Sea found the most energetic neutrino to date. And scientists are still talking about it because, well, this discovery could be a really ...

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

High-energy astrophysics investigates the most energetic processes in the Universe, from the acceleration of charged particles in supernova remnants to the production of ultra-high-energy neutrinos ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...

The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

Supermassive black holes are some of the most powerful engines in the universe. These giants sit at the centers of galaxies, including your own Milky Way, and sometimes become active by pulling in ...
