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 rays seen at Earth show a wide range of particle energies, from 10 7 electron-volts (eV) to more than 10 20 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

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 ...

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 ...

An illustration of a young solar system immersed in high-energy cosmic rays from a nearby supernova. Unlike considering only direct injection of supernova ejecta, this process naturally explains key ...

Japanese researchers developed a system based on subatomic particles derived from high-energy cosmic rays to locate a person's position underground, something that existing navigation tools like GPS ...

Ultraheavy particle clue: Penn State-led research suggests some ultrahigh-energy cosmic rays are made of nuclei heavier than iron, altering theories on their origins. Record-breaking events: The 2021 ...
