excellent job of deflecting these potentially harmful rays and particles,
including those from the sun.
Particles discharged from the Sun travel 93 million miles (around 150
million km) before they are drawn irresistibly towards the Earth’s
magnetic north and south poles. As the particles pass through the
Earth's magnetic shield, they mingle with atoms and molecules of
oxygen, nitrogen and other elements that result in the dazzling display
of lights in the sky.
