Nov 9, 2023 · The purple light streak, often bordered by patches of green, is a result of magnetic storms, which are commonly caused by outbursts of plasma from the sun and have been known to disturb GPS ...

Feb 26, 2024 · Depending on their intensity, the lights might be just a patch of band on the northern horizon; at higher intensities the northern lights can fill the entire sky. The lights will usually be white or a pale green, but will sometimes appear in colors such as yellow, red, blue, or …

The collisions produce light much like how electrons flowing through gas in a neon light collide with neon and other gasses to produce different colored light bulbs. The Aurora is also called the Northern Lights in the northern hemisphere and Southern Lights in the southern hemisphere.
