What is the material of aurora? In fact, many people have different views. Some people think that the theme of electromagnetic field is very active in the north and south poles of the earth, so the electromagnetic field and the gas in the air will have an effect and produce colorful aurora. That statement is not very accurate, but you can also master some conversion characteristics of aurora from it! Then, some people think that it is the cyclone-themed activities in the polar regions of the earth, which often lead to some hurricanes. Then this cyclone will intersect with natural light, because that intersection will cause friction and lead to friction charging and discharging, so everyone will see beautiful aurora!
Naturally, some people say that the atmosphere of the earth's north and south poles is much thicker than other regions, so the ability to map the sun's rays will be very strong. At the same time, most of the light shining on the north and south poles will be reflected back, thus producing aurora! Although the above statement is not very accurate, it also gives you a reliable basis for scientific research on aurora!
What is the aurora? Aurora is actually high-energy particles from the sun, which gather to the north and south poles under the action of the earth's magnetic field and collide with particles in the earth's atmosphere. Aurora is a colorful lighting condition, which often appears in the air with high magnetic latitude. It is caused by the high-band particle flow in the sunlight area or the molecular structure or molecular excitation in the upper atmosphere! Due to the effect of the earth's magnetic field, this kind of high-energy particles are transferred to the polar regions, so aurora can often be seen in high magnetic latitudes! We can sum up that the three standards caused by aurora are air electromagnetic field and high-band particles!
Simply put, aurora is an optical phenomenon excited by charged particles blown by solar storms and atoms and molecules in the upper atmosphere of the earth (above the ground 100-200 km). There are three important processes in the formation of aurora: charged particles generated by the solar wind, charged particles attracted by the earth's magnetic field to the north and south poles, and excited by the operation of atmospheric components. The so-called "solar wind" is an energy that the sun constantly radiates to the universe. It consists of electrons and protons. Due to the intense activity of the sun, countless charged particles are emitted. When charged particles flow to the earth and enter the range of the earth's magnetic field, they will enter the upper atmosphere near the north and south magnetic poles at high speed along the earth's magnetic field lines, and collide with particles such as oxygen atoms and nitrogen molecules, resulting in "electromagnetic storms" and "visible light" phenomena, which become a striking "aurora".
There are some legends about the aurora:
One day that has been circulated for thousands of years, night came. As the sun sets, the night has spread its gray-black wings in the north and south of the Yangtze River, covering mountains and rivers, trees, rivers and mounds, all of them. A young woman named Fu Bao was sitting alone in the wilderness, and a bay of rain under her eyebrows was as enthusiastic as fire. Obviously, she was deeply attracted by this quiet night. The starry sky looks like a Wang Yang. Quiet and mysterious. On the awning, endless space 2 is swaying, quietly overlooking the dark road. Suddenly, in the constellation Ursa major, a wonderful ray of light like a rainbow of seven colors floated out, like smoke and fog, swaying, moving and static, and finally turned into a huge halo, winding around the Big Dipper.
At that time, the color of the ring was greatly improved, just like the bright moon hanging in Clear Sky in Wan Li, which poured a touch of silver light on the ground and lit up all the fields. Everything in the world is clear, so everything becomes abrupt. Attached treasure saw this scene and could not help but be moved. So I got pregnant and gave birth to a baby. This boy is the Yellow Emperor Xuanyuan. This may be one of the oldest fairy tales about the aurora in the world.
Aurora is also described in China's ancient book Shan Hai Jing. It is mentioned in the book that there is a fairy in the northern region who looks like a red snake and shines in the night sky. Its name is Molong. There is the following narrative about touching the dragon: "The human face is snake-shaped, latosolic red, and the body length is Wanli, the king of Zhongshan." Touching the dragon here is actually the aurora.
How's it going? Have you ever been shocked by this magical light? It is difficult to see the best aurora, because it is greatly influenced by weather and environment. The best viewing time is between September of each year and April of the following year. You can choose to watch it in Canada, Russia, Norway, Iceland or Antarctica, which is far away from city lights.
