Source link Recently, scientists have made a significant discovery surrounding cosmic rays. Cosmic rays are energetic particles that originate outside the Solar System and have puzzled astronomers for years.

A team of researchers have detected an anomalous near-Earth cosmic ray contribution resulting from previously unrecognized sources in the local Galactic plane. This is a significant discovery in uncovering the origin and nature of cosmic rays, and their role in the universe.

These cosmic rays are energetic particles that come from space, usually from supernova shock waves or the active centers of galaxies. In the past, astronomers have investigated the origins of cosmic rays by tracking their energy levels, composition, and trajectory. However, astronomers had never studied the near-Earth population of cosmic rays before.

The recent observation of these newly discovered near-Earth cosmic rays provides a more complete picture of their origin and can help scientists better understand their role in the universe. These particles also help form the Earth’s radiation belts, which affect satellite communication, electronics, and power systems.

The research team collected data from the Alpha Magnetic Spectrometer (AMS), a device that is mounted on the International Space Station and has the capability to measure incoming particles in the form of cosmic rays.

The data from the AMS showed a pattern that was different from ones recorded in the distant universe. It appears that these previously unrecognized sources of cosmic rays may come from the local Galactic plane and have a much higher energy level than those found other places.

The discovery of near-Earth cosmic rays could shed light on the source of energetic particles in the universe. This research will help scientists better understand the origin, production, and transport of these particles, and the impact of their energy on the Earth.

Overall, the discovery of near-Earth cosmic rays is a major breakthrough in understanding their role in the universe. The knowledge gained from this research will continue to improve our scientific understanding of cosmic rays and their relation to the natural world.
