There is a hole in the earth's magnetic field. Why is there a pink aurora?
When charged particles from the sun attack the earth, the earth's magnetic field will guide these charged particles to the polar regions, and these charged particles will pass through the atmosphere, which will heat atoms in the atmosphere to form auroras. Aurora is not only a beautiful landscape, but also a proof that the earth's magnetic field protects us and electronic equipment from radiation.
The aurora on the earth is mainly green, because the atmospheric region where the solar wind can reach is rich in oxygen atoms. When the oxygen atoms are heated and excited by charged particles, green light will appear, but when there is a hole in the protection of the earth's magnetic field, we can see that the aurora emits unusual colors! Pink aurora appears in the North Pole of the earth:
The earth's magnetic field can protect the earth from the direct influence of solar storms, but powerful solar storms can also lead to cracks and holes in the earth's magnetic field. Charged particles from solar storms penetrate deep into the earth's atmosphere, and richer colors will appear.
The Norwegian tour group in the North Pole of the Earth photographed the pink aurora lasting for 2 minutes in the North Pole. Through the color of aurora, we can judge the stratification of the earth's atmosphere.
The pink aurora is mainly caused by the cracks or holes in the earth's magnetic field caused by the solar storm. The breakthrough of the earth's magnetic field allows the charged particles of the sun to penetrate deep into the atmosphere, pass through the area rich in oxygen atoms, and enter the atmospheric area with more nitrogen atoms. When the nitrogen atoms are heated and excited, pink light will appear.
By observing the stratification of pink aurora, we can see that the aurora near the earth's surface is pink, and the aurora near outer space is still ordinary green. The hole in the earth's magnetic field makes the solar storm penetrate into the atmosphere for 1 kilometers:
The pink aurora appears in the North Pole of the earth. According to the investigation of scientists, the charged particles of the solar storm penetrate into the atmosphere for about 1 kilometers, and the atmosphere in this area is mainly nitrogen. After the charged particles smash nitrogen molecules into nitrogen atoms, they excite pink light.
Although the aurora with special colors looks more beautiful and shocking, it also means that the radiation of solar storms is closer to the surface of the earth. The aurora with special colors usually appears when there are cracks and holes in the earth's magnetic field.
The hole in the earth's magnetic field was completely closed about 6 hours after it appeared, but this phenomenon also attracted many astronomy enthusiasts who like aurora, because when there is a hole in the earth's magnetic field, the probability of aurora will be greatly increased, not only the aurora with special colors, but even the aurora will continue to appear all night.
At the same time as the pink aurora appeared, blue light bands appeared in some parts of the Arctic. Although many residents think that the blue light band is also an aurora, astronomers say that the blue aurora has never appeared, so the blue light band is probably the artificial light of the earth or other optical phenomena.
Aurora is the trace of the earth's protection for us. As the most perfect planet in the solar system, the earth not only has sufficient resources, an atmosphere suitable for survival, but also a magnetic field to defend against cosmic radiation. All kinds of miracles in the universe are combined to create a perfect earth.
Although the earth can't be the eternal home of human beings, it is still our only home at present. We need to protect the earth and explore the universe so that human beings can thrive in the universe!
