Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right lighting ...

The KM3NeT Collaboration, operating a partially built neutrino detector on the Mediterranean seafloor off the coast of Sicily, has recorded a cosmic neutrino with an estimated energy of about 220 PeV, ...

Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...

Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Cosmic ray air showers are produced when high-energy cosmic particles enter Earth’s atmosphere and interact with atmospheric nuclei, generating cascades of secondary particles. These extensive air ...

The Universe teems with extreme environments, ranging from the very coldest temperatures to the highest energy sources possible. As a consequence, extreme objects such as supernova remnants, pulsars ...
