The gamma-ray experiment HESS offers compelling evidence of a PeVatron that may help us better understand galactic cosmic rays
Today’s paper investigates the mass composition of galactic cosmic rays using radio astronomy measurements
Does the Sun shine in high-energy gamma rays? Apparently so, in the form of a halo surrounding itself. But certain features of this gamma-ray halo are perplexing.
The moon provides an easy way to detect rare ultra-high-energy cosmic rays.
Cosmic rays hit the Earth and produce showers of particles that can be detected on the ground. Understanding where these cosmic rays come from can help scientists pin down their sources and construct models for the magnetic field in our neighborhood.
