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 inattention is only a scientific explanation, then the phenomenon of the polar aurora is easy to explain. The earth is a huge magnet, the lines of which radiate 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 emit energy, which we see as the light of a wide variety of shades.
It is interesting that the green and red glowappears as a result of excitation of oxygen atoms, infrared and violet - ionized nitrogen molecules. It turns out that the northern lights - the interaction of particles of solar radiation with our magnetosphere.
Dangerous infrasound
It is proved that a polar glow generateslow-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 say that infrasound can have unpredictable effects on the cardiovascular system and the human brain.
In addition, infrasound is the culprit of manycatastrophes that occurred in the sea. It is believed that infrasound within 7 Hz can even lead to the death of a person, as it causes vibration of the internal organs, and this leads to cardiac arrest.
Where and when can I see the northern lights?
Полярное свечение сильно зависит от активности the sun. Accordingly, the higher the latter, the more likely it is to observe this surprising 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 such a phenomenon of nature in the polar regions of northern countries.
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.
