What are Northern Lights? The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres.
One of the most magical, which I have had the good fortune to experience several times, is a marvel that I encourage you to add to your own list: I was working a summer job as a tour guide in Skagway, Alaska. It was the end of August, around 10 pm, and the midnight sun had given way to dark night skies.
Instead, the luminous white glow expanded and took on a slightly greenish cast, and soon the skies over the mountains began to move. I realized I was seeing the northern lights for the first time. The ghostly glow swayed left, then right, undulating like a sheet in the wind. Every northern culture has legends about the aurora.
One Inuit myth holds that the northern lights are torches held in the hands of Spirits seeking the souls of those who have just died, to lead them over the abyss terminating the edge of the world.
Another holds that the lights are the visible spirits of unborn children playing ball in the heavens.
What Causes the Aurora Borealis? The scientific explanation for the lights may be less poetic, though still fascinating. Auroras are born of the sun, when large explosions and flares throw great quantities of particles into space, carried outward by the solar wind.
As they interact with the upper layers of the atmosphere, approximately 60 to miles above our heads, the energy that is then released appears as a luminous, moving glow, typically visible in the night sky in the polar zones at particular times of the year. Each gas gives out a characteristic color when bombarded.
Excited oxygen atoms emit yellow-green light, the most commonly observed color. Ionized molecular nitrogen emits blue and violet light, colors to which the human eye is less sensitive.
At lower altitudes, excited molecules of nitrogen and oxygen glow with a vivid red. These three primary colors together produce the hues of a typical aurora. In the north, it is known as the aurora borealis, named for the Roman goddess of the dawn, Aurora, and the Greek name for the north wind, Boreas.
Especially in Europe, the aurora often appears as a reddish or pink glow on the northern horizon, as if the sun were rising from an unexpected direction.
On September 15,an intense aurora dispatched firefighters throughout London. Because the north magnetic pole lies in North America, the auroral oval generally reaches farther south there. This means observers at a given latitude in North America have a better chance of seeing an aurora than those at the same latitude in Europe or Asia.
In general, you are more likely to see an aurora if you are at a higher latitude, that is, closer to the pole. In Europe, northern Norway generally offers the best location for seeing the lights.'Aurora borealis', the lights of the northern hemisphere, means 'dawn of the north'.
'Aurora australis' means 'dawn of the south'. In Roman myths, Aurora was the goddess of the dawn. \par Many cultural groups have legends about the lights. A Description of Aurora Borealis, a Name Meaning "Northern Dawn" words. 1 page. The Cell: A Miracle of Design.

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights, northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic)..
