The IceCube neutrino telescope encompasses a cubic kilometer of clear Antarctic ice under the South Pole, a volume seeded with an array of 5,160 sensitive digital optical modules (DOMs) that precisely ...

Scientists have received the first transmissions from a muon detector placed 1 km underground in the Stawell Underground Physics Laboratory. The muon detector records the amount of cosmic radiation ...

Cosmic rays are high-energy particles from outer space that strike Earth's atmosphere, generating showers of secondary particles, such as muons, that can reach the planet's surface. In recent years, ...

Physicists have designed a pocket-sized cosmic ray muon detector to track these ghostly particles. The detector can be made with common electrical parts, and when turned on, it lights up and counts ...

Cosmic-ray muons are free, ubiquitous, very penetrating particles. Muon radiography takes advantage of them to probe objects that, because of their thickness or the shielding around them, would be out ...

Researchers have used cosmic rays from deep space to create a powerful probe to investigate the hidden mysteries of the Great Pyramid of Giza. The team, including Fermilab High Energy Physics (HEP) ...

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. In the 1970s, a pioneering ...

Just as dental X-rays find cavities in your teeth, a group of researchers plan to use a natural form of radiation, called cosmic ray muons, to search for cavities in a 2,000-year-old pyramid. The ...

Particles raining down from space offer 3-D views inside swirling tropical storms. Muons created from cosmic rays that smash into Earth’s upper atmosphere have revealed the inner workings of cyclones ...

Georgia State Regents’ Professor of Physics and Astronomy Xiaochun He and his students have developed a detector to measure cosmic rays and investigate how space weather can impact our changing ...
