On the other hand, the ribbons which runs, trap doors of filling swirls, another world of pre-heating, gauze veils, and the brilliant lines of l' northern light are a regular presence which filled with wonder and terrified people of North since d' thousands; years. For the Finns, l' dawn was “fire fox” caused by the fur luisante. Certain Inuits of l' Alaska screw hearts of dance of the stags, of the seals, salmon, and the white whale, d' others believed that, s' they whistled fires likely to tear off them.
Athabascan seen of the messages of their deaths, “inhabitants of the ciel." For a long time, the scientists offered almost as much d' interpretations of l' northern light as the traditional people which observed them.
The 20th century brought with it of the studies on the magnetism of the Earth and the operation of the sun. L' dawn is posed in turbulences which crosses of the sun. More than 100.000 times hotter than l' ebullient water, chops of l' interior of the Sun, atoms that gases in solar form in a thin net of particles electrically charged - protons and electrons. Time of the matter and d' energy, this course d' water spouts out permanently by the sun and is called the solar wind. Two or three days after l' bursting of the surface of the sun at speeds active jusqu' with 500 miles a second, the solar wind reaches the Earth, 93 million miles.

Solar wind with the force to quickly destroy the life on ground. Qu' be-EC qu' it s' stop doing it is the power of shielding of magnetic field of planet, to reach more than 40.000 miles in l' space. Like the ground, the sun is also loving powerful, and the solar wind transports fragments of its magnetic field. Like collision of solar particles in the magnetic field of planet, the fields are pushed back mutually. Although the majority of the solar wind sideswipes without danger the magnetic shield, of small brooks of solar particles arrive to s' there to wedge, spiralling towards north from planet and the magnetic south pole.
Like they linen, propagation of the beams d' electrons, undulation and swirl, and yet their movements remain invisible. But when the solar wind strikes the upper part of l' ionosphere and of meetings of atmospheric gases, it starts with churning of the clear soup of l' oxygenate and l' nitrogenize there. Marvelous forms and of the models which runs start to appear. Balloté enters the electrons of the atoms d' oxygenate to create a greenish gleam, much low. Molecules d' nitrogenize struck by the solar wind May to shine pink or blue and the purple one, according to their distance from surface.

The dance always changing the light gives a false idea of permanence of l' Aurora. Although parts can be consulted constantly, and almost never the day, l' northern light forms one 2.000-mile oval auroral broad above the magnetic north pole day after day, year after year. What can change l' radically; oval are the occasional points of l' solar activity, which transforms the solar wind in a hurricane which makes rage. Then, during a few days, auroral oval flows towards l' Ecuador and the draft-sky idlers as far in the south as Mexico with extravanganzas midnight
. In same time, the electromagnetic disturbances s' to intensify, with electric lines overloaded and scrambled communication with the service to recall us the force behind fires d' celestial artifice.
