The flickering lights over our northern- and southern-most skies at times seem like a mystical offering. Good ole northern lights (aurora borealis) and southern lights (aurora australis), visible 65 to 72 degrees north and south latitudes respectively, are actually just natural light shows that exist in our ionosphere. Scientists say auroras are created when a solar wind of charged particles from the sun crashes into the Earth's upper atmosphere over the polar regions. And so, auroras are generally spotted closer to the north or south poles. You can see them here.
