Coverage is expanded to include new content on high energy physics, the propagation of protons and nuclei in cosmic background radiation, neutrino astronomy, high-energy and ultra-high-energy cosmic ...

High-energy particles, known as cosmic rays, provide a window into some of the most extreme environments in the universe.

DURING the examination of about three thousand cosmic stars in Ilford G5 plates 200µ thick, exposed at balloon altitude, we observed in several cases two prongs of comparable length, making a ...

The study suggests that some recent observations of "antinuclei" in cosmic rays are consistent with the existence of WIMPs, ...

By studying this antimatter production, scientists explore the composition of cosmic rays and their distribution across the universe. Pulsars like PSR B2224+65 act as “blowtorches,” dispersing ...

They've detected the most energetic cosmic electrons ever observed, unlocking new avenues in our understanding of the universe. "Cosmic rays are a century-old mystery," Mathieu de Naurois, a ...
