For the first time, astronomers have spotted enormous, galaxy-scale shock waves rattling the "cosmic web" that connects nearly all known galaxies. These cosmic waves could reveal clues about how the ...

For the first time, astronomers have caught a glimpse of shock waves rippling along strands of the cosmic web — the enormous tangle of galaxies, gas and dark matter that fills the observable universe.

NASA's Juno spacecraft caught Jupiter's magnetic shock wave accelerating particles to nearly the speed of light. The same ...

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

For many years, scientists have been trying to understand cosmic rays—tiny, fast-moving particles that stream through space and bombard Earth nonstop. These high-energy particles are linked to ...

For more than a century, cosmic rays have remained one of astronomy’s lingering puzzles. These tiny particles move through space carrying extraordinary amounts of energy, arriving from distant corners ...
