Archaeologists and physicists have achieved a breakthrough in historical exploration by using cosmic-ray muons to map subterranean structures in Jerus.

Muons continually bombard the ground at a known rate and angular distribution. As muons lose energy when passing through matter, their flux is attenuated depending on the integrated density along ...

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 ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics. Every minute, countless muons rain down from space, passing through ...

New analyses by the IceCube observatory could help scientists understand where neutrinos form and what is producing them ...

Cosmic rays are mainly high-energy protons produced by galactic events, such as shock waves from exploding stars (supernovae). Traveling at almost the speed of light, they collide with particles in ...
