When you gaze at the mighty Great Pyramid of Giza—sometimes called the Pyramid of Khufu—you’re looking at four and a half millennia of human effort. And in 2017, researchers revealed there’s more than ...

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 ...

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 ...

Cosmic rays from supernovas will help secure the supply of crucial minerals.

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 ...

Cosmic ray muons are elementary particles generated from high-energy collisions in the upper atmosphere. In an effort to make particle physics research more accessible to undergraduates, we have ...
