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 ...

At 10 a. m. on Jan. 1 the high-banked seats of a lecture amphitheatre at Washington University were jammed with a capacity crowd of 300—mostly scholars, a few newshawks, a handful of laymen. In the ...

As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier. As ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

China’s Large High Altitude Air Shower Observatory (LHAASO)–one of the country’s key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic ...

High energy astrophysics studies the most violent processes in the Universe, from supernova explosions and pulsar winds to active galactic nuclei and cosmic‐ray acceleration. Galactic cosmic ...

How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies ...
