SPACE WEATHER AURORAS
The amazing, colorful, and dancing auroras we see from time-to-time are the result of incoming energy and particles from the sun.
NASA informs us that energy and solar particles leave the sun periodically; this energy and the solar particles can take two to three days to arrive at Earth. Quite a trip! Once they do arrive, though, our upper atmosphere reacts with them. The reaction includes oxygen and nitrogen molecules releasing myriad photons of light. This then, causes the so-called Northern and Southern lights.1 Cool, eh?
According to NASA, auroras are part of "a larger space weather system in which solar material and radiation can affect Earth's own magnetic environment and block radio communications, disturb onboard satellite computers, or — at their worst — cause electrical surges in power grids."2
