Northern lights: what an amazing phenomenon?

Northern lights shine with their beauty. Our ancestors believed that this extraordinary phenomenon brings to man a threat and misfortune. Many residents of northern countries are still convinced that seeing the aurora is a bad sign. Is this phenomenon really harmful? Or is it just a fiction of ancient peoples?

Why are the aurora borealis?

If you drop all myths and legends, and take into account only a scientific explanation, then the phenomenon of polar lights is easy to explain. The earth is a huge magnet, the lines of which are radiated from the North Pole region, encircle the entire planet and exit into the South Pole. The sun "supplies" the earth's surface with a stream of electrons and protons, these particles, reaching the lines of force, ionize molecules and atoms of gases. Charged molecules and atoms begin to radiate energy, which we see as the light of a wide variety of shades.

It is interesting that the green and red glow appears as a result of excitation of oxygen atoms, infrared and violet - ionized nitrogen molecules. It turns out that the northern lights - the interaction of solar radiation particles with our magnetosphere.

Dangerous infrasound

It is proved that polar radiation generates low-frequency magnetic waves. They emit in the range of about 8-13 Hz, which is akin to some rhythms of the brain. This phenomenon is also accompanied by biologically active infrasound. Scientists claim that infrasound can have unpredictable effects on the cardiovascular system and the human brain.

In addition, infrasound is the culprit of many disasters that occurred at sea. It is believed that infrasound within 7 Hz can even lead to the death of a person, since it causes vibration of the internal organs, and this leads to cardiac arrest.

Where and when can I see the northern lights?

Polar glow strongly depends on the activity of the sun. Accordingly, the higher the latter, the greater the chance to observe this amazing phenomenon. The sky must be clear, and the weather - frosty. The best time to meet with him is from 10 pm to midnight. The Northern Lights (photo demonstrates this phenomenon in all its glory) is best observed from October to January.

You can see this phenomenon of nature in the polar regions of the northern countries.

1. Norway. In addition to the northern lights, there is another unique phenomenon - daylight of a saturated blue color.
2. Iceland. True, it is very difficult to see the aurora borealis in the cities, most often it can be seen outside the populated areas.
3. Finland (northern regions). This country has a low level of air pollution, so the northern lights can be seen 200 times a year.
4. Russia. In our country, this phenomenon is observed in Yakutsk, Murmansk, Salekhard, in Taimyr and in other northern regions.
5. Alaska.
6. Sweden (Kiruna).
7. Greenland (southern part).

The natural phenomena are truly amazing! The northern lights fascinate millions of people with their beauty. Many people dream of seeing this amazing phenomenon with their own eyes. Anyone who has ever seen this miracle of our planet will never forget it.
