While the name suggests "rays," cosmic rays are actually high-energy particles, primarily protons and atomic nuclei. These particles originate from various sources in space, including supernova explosions, active galactic nuclei, and the Sun.
Here's a breakdown of the different types of cosmic rays:
* Galactic cosmic rays: These are the most common type and originate from sources outside our solar system.
* Solar cosmic rays: These originate from the Sun, particularly during solar flares and coronal mass ejections.
While they are a constant phenomenon, cosmic rays are not always harmless. They can pose a health risk to astronauts and passengers on high-altitude flights, and they can also disrupt electronic systems. However, Earth's atmosphere provides some protection from these particles.
