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 ...

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, ...

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 ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

The sprawling Auger Cosmic Ray Observatory in South America has produced its first major discovery while still under construction. The international Auger collaboration has traced the rain of ...

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

"You know we haven't done enough research into the effects of cosmic rays!" Ben Grimm, Fantastic Four #1, 1961 Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of ...
