The IceCube neutrino detector has allowed researchers to resolve a debate about what types of particles make up ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the ...

Lightning is the most spectacular manifestation of atmospheric electricity”, yet its precise trigger has long eluded science.

Neutrinos are subatomic particles with no charge and very little mass that are known to weakly interact with other matter in ...

Once completed, 500 new detectors will allow the Telescope Array to capture cosmic ray-induced particle showers across 1,120 square miles — an area nearly the size of Rhode Island, according to ...

Cosmic rays are like sparks from a massive stellar crucible — each contains flecks of material from the forging process. Gamma rays are more like light from a glowing hearth.

By building and operating your own cosmic ray detector, you can gain hands-on experience with electronics, programming, and data analysis.

CAPE CANAVERAL, Fla. (AP) — Spacewalking astronauts worked to complete repairs to a cosmic ray detector outside the International Space Station on Saturday and give it new life. It was the ...

In this pre-pandemic photo, UD postdoctoral researcher Alan Coleman stands by one of the Pierre Auger Observatory’s 1,600 cosmic ray detector stations, which are spread out across 1,200 square miles ...

The emulsions, initially, revealed that over 90% of cosmic rays were actually protons, with most of the rest being heavier atomic nuclei, like alpha particles (helium-4 nuclei).

Cosmic rays affect these, too, but the mechanism is completely different. The impact of a cosmic ray also creates vibrational energy, which takes the form of something called phonons.
