In a collaboration showing the power of innovation and teamwork, physicists and engineers at the Department of Energy's Oak Ridge National Laboratory developed a mobile muon detector that promises to ...

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts ...

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 ...

Physicists have for the first time detected cosmic rays using the trail of radio waves they leave in ice. Researchers hope that honing this technique will help them to spot a more exciting prize: ...

Cosmic rays (CRs) are particles that travel through space at nearly the speed of light. They are mostly protons (\(\approx\) 90%), but also include heavier atomic nuclei (\(\approx\) 9%), ...

We are zeroing in on the true composition of the rarest, highest-energy cosmic rays – which could help reveal their unknown origins. Previous ultra-high-energy cosmic ray detections – by the Pierre ...

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 ...
