In the night skies of far northern regions, shimmering waves of shifting colors will sometimes emerge from the horizon. This mysterious light show, called the aurora borealis, has been a source of stories and inspiration for thousands of years. It is the result of the earth periodically crossing into the path of the sun's charged particle flows, which causes our magnetic field to react by lighting up.
Even with this clear scientific explanation, the experience of viewing the aurora borealis and seeing the movement of the earth's magnetic field is still profound.
