Question

Difference between galactic and extragalactic cosmic rays

Answer 1

Answer:

EXTRAGALACTIC COSMIC RAYS:-

Extragalactic cosmic rays are very-high-energy particles that flow into the Solar System from beyond the Milky Way galaxy. The energies these particles possess are in excess of 1015 eV.

GALACTIC COSMIC RAYS:-

Galactic cosmic rays (GCRs) come from outside the solar system but generally from within our Milky Way galaxy. GCRs are atomic nuclei from which all of the surrounding electrons have been stripped away during their high-speed passage through the galaxy.
