How is the Northern lights
For centuries people have looked to one of the natural wonders on Earth — the Northern lights, not knowing what it is. Ancient peoples, for example, had their own explanation: Inuit tribes believed that the light emitted from the souls of the dead on the way to heaven, and in medieval Europe believed that this is the battle that doomed forever to lead a died in the battle of warriors.
Scientists and researchers have come to a solution a little closer — they have advanced the theory that the Northern lights are caused due to reflection of light from ice caps. Galileo called this phenomenon the Aurora after the Roman goddess of the morning, after he concluded that it arises from 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 from our atmosphere — the energy from the collisions is released as light. The fact that the Northern lights occur mostly at the poles, because there the Earth's magnetic field is particularly strong.
In 2008-m to year, scientists from Los Angeles, concluded that when two magnetic field lines appropriately interact with the accumulated solar energy that reaches a critical limit, and in the case included the power of magnetic field energy, whereby magnetic energy is converted into kinetic energy and heat.
Most likely to see the Northern lights in winter, the particular position of the Earth relative to the Sun — when the days get short, the nights are usually darker. By the way, the Northern lights is not only at the North pole, but in the South too. On other planets, including Mars, the Northern lights too, so you can be sure that the next generation born on other planets, will be able to witness such awe-inspiring phenomena.
If you haven't seen the Northern lights, it's time to plan a trip: scientists predict that this December will be the best period for such observations for all the next decade due to the high level of solar activity.
