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 ...

In a significant breakthrough, scientists have unraveled the mystery of cosmic rays, linking the ‘knee’ formation in their ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

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 ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

China’s Large High Altitude Air Shower Observatory (LHAASO), a major scientific infrastructure, has released groundbreaking results from its "Mini Survey of the Milky Way" program. With unprecedented ...

James Webb Space telescope spots 'big red dot' in the ancient universe: A ravenous supermassive black hole named 'BiRD' ...

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 ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...

The "bone" is actually a galactic center filament, and it's about 230 light-years long. Have you ever had an X-ray taken of your bones? Well, so has the Milky Way. NASA's Chandra X-ray Observatory ...
