Cosmic rays are high-speed particles created by supernova explosions and other space interactions, carrying elements that can ...

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 ...

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life.

Our planet has recently been struck by an extraordinary burst of cosmic rays, demonstrating an intensity level that is unparalleled in recorded history. As we delve into the specifics of this event, ...

Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, ...

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 discovery could transform how researchers monitor and forecast solar storms that have harmful effects on satellites, communication systems, and power grids.

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 ...

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 ...

Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...
