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 ...

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 ...

China’s Large High Altitude Air Shower Observatory (LHAASO)–one of the country’s key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic ...

Fermilab’s Mu2e experiment has reached a critical assembly stage with its 60-ton cosmic-ray veto system in the detector hall, ...

(a)The UHE gamma-ray emission is clearly observed from the W51 complex, which hosts the supernova remnant W51C and star forming region W51B. (b) The “bending” feature around tens TeV indicates the ...

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays. Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in ...

The most energetic particles in the universe – ultrahigh-energy cosmic rays – likely come from supermassive black holes in the hearts of nearby active galaxies, says a study by scientists from nearly ...
