-ray Cosmic ray is a form of high energy radiation that originates from outside the solar system. It consists of particles, mostly protons and electrons, travelling at nearly the speed of light. Cosmic rays are a natural source of radiation that can be found almost everywhere on Earth. They have been studied for many years and are known to have an effect on the environment and human health. Cosmic rays can be used to study the structure and composition of matter in space as they interact with it when passing through it. They can also be used to detect cosmic events such as supernovae or gamma-ray bursts, which emit large amounts of energy in short bursts. Cosmic rays also provide clues about the origin and evolution of our Universe by providing information about how it was formed and how it has changed over time. Cosmic ray detectors measure the intensity, direction, energy spectrum, and composition of cosmic rays as they pass through our atmosphere or travel through space near Earth. These detectors are located all around the world in different locations such as mountain tops or underground laboratories where they are protected from other sources of radiation. This allows scientists to study cosmic rays from different angles and gain a better understanding about their properties and effects on our planet.
