Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters, and teach some of us more than we can ever learn from books.Mythology
~ John Lubbock
- The Algonquins of North America believed Nanabozho, after creating earth, went to the far north to build great fires reflecting southward as an expression of lasting love.
- The Finnish word for the northern lights translates to Fox Fires originating from a Finnish fable. In the fable, the lights were caused by a fox sweeping his tail across the snow spraying it into the sky.
- The Saami, indigenous arctic people, believed the lights to be blazing fires from the souls of the departed and to disrespect the fires would lead to bad fortune.
There wasn't a scientific rationalization of the Northern Lights until French geophysicist Jean-Jacques d'Ortous de Mairan linked auroras to solar activity in 1774.
An aurora is a display of light in the sky prevalent in the high latitudes. The light emanates from the collision of energetic charged particles with atoms in the high altitude atmosphere. The charged particles originate in the magnetosphere and from solar wind. The Earth's magnetic field draws the particles into the atmosphere. During a geomagnetic storm, the visible auroral zone expands into lower latitudes.
NASA Crew Earth Observations uploaded the following video sequence of an aurora over the Great Lakes and Canada.
