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 ...

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 ...

Cosmic ray energies are measured in electron volts, a unit describing the energy an electron gains when its electrical potential increases by one volt. "The highest energy of galactic cosmic rays can ...

Cosmic rays are relativistic charged particles that pervade the Galaxy and beyond, carrying crucial information about violent astrophysical processes and influencing the dynamics of interstellar and ...

A new observatory is set to detect sources of cosmic rays, dark matter and other relics of the Big Bang in a few years' time.

Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better ...

On Earth, the Large Hadron Collider can smash atoms together and accelerate particles to near light speeds — but in space, there are high-energy cosmic rays with over 10 million times more power than ...

The failure of ghostly subatomic messengers called neutrinos to show up at an Antarctic telescope has knocked down a major astrophysical theory involving some of the most dramatic explosions in the ...

Cosmic rays are high-energy particles, chiefly protons and atomic nuclei, that pervade space and strike the Earth’s atmosphere. Detection techniques encompass ground-based air-shower arrays, ...
