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 ...

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, ...

Many massive stars explode as supernovae. If cosmic-ray baths are common in such environments, then the thermal histories that shaped Earth's interior may be common as well. This realization has ...

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, ...

For more than 60 years, physicists have chased one of the universe's most stubborn puzzles: where do the most energetic particles ever detected come from? A new study published May 7, 2026, in ...
