<p>A major defense against everything space throws at us, Earth&rsquo;s magnetic field may even protect the moon from damaging galactic cosmic rays</p>
The Earth's magnetic field is a protective shield generated by the movement of molten iron in its outer core. It plays a crucial role in protecting the planet from solar and cosmic radiation, as well as guiding navigation for various species and human technologies.
Cosmic rays are high-energy particles that originate from outer space and strike the Earth's atmosphere. They are primarily composed of protons and atomic nuclei and can provide valuable information about astrophysical processes and the universe's origins.
