Around 10,000 muons pass through each square meter of Earth’s surface every minute, creating a natural particle shower that researchers are now using to read the interiors of monuments without cutting ...

In the stone mass of the Great Pyramid, a corridor about 9 meters long was outlined not by drills or demolition, but by particles raining down from space. Later confirmed with radar, ultrasound, and ...

Muon radiography and tomography are innovative non‐destructive imaging techniques that employ cosmic-ray muons to probe the internal structures of large objects, from ancient monuments to active ...

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 ...

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 ...

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 ...

Under cover The new transfer-learning system could be used to identify shipments of illicit nuclear materials. (Courtesy: Shutterstock/Gualtiero Boffi) Machine-learning could help us use cosmic muons ...
