 Cosmic-ray observatory

A cosmic-ray observatory is a facility designed to detect and study cosmic rays, which are high-energy particles originating from outer space. These particles primarily consist of protons, atomic nuclei, and high-energy electrons, and they can arrive at Earth from various sources, including supernovae, active galactic nuclei, and even our Sun. Cosmic-ray observatories employ a variety of detection techniques and technologies to observe these particles.
