How does the aurora borealis

The light emitted by the souls of the dead on the way to heaven or eternal echoes of battle knights Srednevekovya
For centuries, people looked at one of the natural wonders of the world - the Northern Lights, not knowing what it is. Ancient peoples, for example, had his own explanation: Eskimo tribes believed that it is the light emitted by the souls of the dead on the way to heaven, and in medieval Europe believed it - a battle that forever doomed to lead the soldiers who died in battle.
Scientists and researchers have come a little closer to a solution - they have advanced the theory that the aurora borealis occurs due to light reflection from the ice caps. Galileo named the phenomenon Aurora after the Roman goddess of the morning, after concluded that it is the result of refraction of sunlight in the atmosphere.
Modern scholars believe that the lights in the sky caused by the collision of electrically charged solar particles and atoms of our atmosphere - the energy of the collision is released as light. The fact that the aurora borealis occurs mainly at the poles, due to the fact that there are Earth's magnetic field is particularly strong.
In 2008, scientists from Los Angeles concluded that when two magnetic field lines properly interact with the accumulated solar energy, it reaches a critical limit, and in the case included power energy of the magnetic field, causing magnetic energy is converted into kinetic energy and heat.
It is most likely to see the Northern Lights in the winter due to the special position of the Earth relative to the Sun - when the days are getting shorter, the nights are usually darker. By the way, the aurora borealis is not only at the North Pole, but also on the south too. On other planets, including Mars, northern lights too, so you can be sure that subsequent generations born on other planets, will be able to witness these spectacular events.
If you have not seen the Northern Lights, it's time to plan a trip: scientists predict that in December this year will be the best period for these observations for all the next decade due to the high level of solar activity.
