Energetic particles that pop briefly into existence when cosmic rays hit Earth’s atmosphere could help assess hidden damage to buildings in Ukraine after the war ends. These particles — known as muons ...

Due to government shutdown restrictions currently in place in the US, the researchers who headed up this study have not been able to comment on their work Laser plasma acceleration (LPA) may be used ...

In a muon tomography detector, cosmic-ray muons interact with an object and strike scintillators that emit photons. Wavelength-shifting fibers transmit the photons to photodetectors that digitize the ...

An incredibly fast-moving particle from space recently arrived on Earth, and physicists are rushing to figure out what it is and where it came from. Called the Amaterasu particle, after the Shinto ...

Astronomers have detected the second most powerful cosmic ray ever recorded, but it seems to have come from an empty region of the universe known as a cosmic void, where there is nothing obvious it ...
