aurora polar

Called an aurora polar aurora borealis in the northern hemisphere and southern aurora in the southern hemisphere, it is a luminous phenomenon by types of extremely colored veils in the night sky.
This veil is caused by the interaction between the charged particles of the solar wind and the high atmosphere, the auroras mainly produces in the regions near the magnetic poles, in an annular zone just "auroral destined area" (between 65 and 75 ° latitude) Magnetic)
It is thus formed in the regions of high latitudes of the Earth and appears in many different forms.
The length of the aurora can measure several thousand kilometers, but its limit can not exceed 100 meters.
The deep movements of creation of auroral stories are a subject of study that scientists have had for years.
