As solar wind approaches the Earth, it meets the Earth’s magnetic field In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth’s atmosphere The energy released during these collisions causes a colorful glowing halo around the poles—an aurora
Is the aurora borealis man made?
