What do you think the Northern Lights are in their form of existence?

The Northern Lights are supposed to exist in the form of molecules or ions, as they are produced by the moleculeization or ionization of the upper air.

Due to the intense activity of the sun, countless charged particles are emitted, and when the charged particles flow to the earth and enter the range of the earth's magnetic field, under the influence of the earth's magnetic field, they will enter the upper atmosphere near the north and south magnetic poles along the earth's magnetic field lines at high speed, and collide with oxygen atoms, nitrogen molecules and other particles, thus producing the phenomenon of "electromagnetic storm" and "visible light", which becomes the "aurora" that attracts everyone's attention.

It is because the Northern Lights are produced by the refraction and decomposition of the atmosphere, which is very rare.

Aurora is a brilliant and colorful luminescent phenomenon that occurs due to the sun's stream of charged particles entering the earth's magnetic field, and the brilliant and beautiful brilliance appears at night at high altitude in the area near the north and south poles of the earth.

Auroras are luminous phenomena caused by charged particles emitted by the sun hitting the ionosphere of the Earth's outer atmosphere, similar in principle to fluorescent tubes.

Hello subject!

Auroras are optical phenomena that are excited by atoms and molecules operating in the uppermost layers of the Earth's atmosphere (100-200 kilometers above the ground), but they are extremely rare. ‍

The Northern Lights are a very sacred, magical existence, and I may not go to the North Pole in my life, I can only see it, not with my own eyes.

A particularly beautiful existence, like a shooting star, can bring good luck to people and can place good wishes on people.

I saw a ** piece on the Internet before, which was to see the aurora in Norway**, the light on it was colorful. It's wonderful. I wondered how such a wonderful natural phenomenon could exist.

It's beautiful, it's distant, and it feels like it's fake, but it also feels like nature is so magical.

Whether you have seen it or not, whether you admit it or not, it will always exist.

The Northern Lights are very, very sacred to me, and even though I haven't seen them, I still love them.

Dark matter, if conditions permit, is the Northern Lights.

The reflection of the light of Elysium. Agree.

The aurora is a celestial reaction.

is a more magical existence, because I probably won't have the opportunity to go to the North Pole to see it in this life, and I can only see it on TV.

Aurora is a natural astronomical wonder, it has no fixed shape, the color is not the same, the color is green, white, yellow, blue, even.

It will also appear in a gorgeous reddish-purple color, graceful and mysterious and unpredictable. The occurrence of the aurora can only be witnessed in the cold autumn and winter nights, high latitudes, because the northern lights are most likely to appear in the dark and cold nights, so the best time is from November to February from 10 pm to 2 am, and sometimes it can last for about 1 hour.

Generally speaking, the types of auroras can be divided into four types: arc aurora, ribbon aurora, curtain aurora, and radial aurora. The northern lights that occur in the north are called the Northern Lights, and those that occur in the south are called the Southern Lights.

Because it can only be seen in certain places. Talking about rare and strange things, and seeing less is naturally a strange phenomenon.

The Northern Lights are rare, so it's a sight to behold.

Auroras are caused by a stream of charged particles from the sun entering the earth's magnetic field and converging high in the sky near the north and south poles of the earth.

The North Pole and the South Pole as tourist destinations, because these two places will have beautiful aurora lights at one time, this is an attraction that attracts people. So how are the auroras formed?

01 It is called the Southern Lights in the South Pole and the Northern Lights in the North Pole. Earth's aurora is produced by the excitation (or ionization) of molecules or atoms in the upper atmosphere by a stream of high-energy charged particles (solar wind) from the Earth's magnetosphere or the Sun.

02 Auroras often appear in the sky above the geomagnetic pole at latitude, generally in the form of bands, arcs, curtains, and radials, and these shapes are sometimes stable and sometimes change continuously. There are three conditions for the formation of auroras: the atmosphere, the magnetic field, and high-energy charged particles.

03 Modern physics has a detailed description of the principle of aurora, and the aurora on the earth is caused by the luminescence caused by charged energetic particles from the magnetosphere and the solar wind being guided into the earth's atmosphere by the geomagnetic field and colliding with atoms in the upper atmosphere (thermosphere). Auroras are not only found on Earth, but also on other planets in the solar system that have magnetic fields.

04 According to research on the distribution of auroras, the shape of the aurora region is not a ring centered on the geomagnetic pole, but an oval shape. The spectral line range of the aurora is about 3100 6700 angstroms, of which the most important spectral line is the 5577 angstroms oxygen atom green line, which is called the aurora green line.

05 Most auroras occur 90-130 kilometers above the Earth. In 1959, a Northern Lights measured at an altitude of 160 kilometers and a width of more than 4,800 kilometers. But some aurora lights are much higher, reaching heights of more than 560-1000 kilometers.

1. The convergence effect caused by the deflection of the electrons coming from the sun approaching the geomagnetic field and the concentration of the magnetic poles in a spiral. In order to pass through the discharge of the extremely thin and coldest layer of the high atmosphere, it causes a magnificent luminescence phenomenon in the atmosphere. The shape has arches, bars and mist, etc., and the states range from beating, flickering to **.

Auroras are usually white to green, red, yellow, blue, purple or pink in color and last from a few hours to a few days.

2. The earth has a strong magnetic field, and the charged particles from the sun are affected by the earth's magnetic field, due to the effect of the convergence of magnetic field lines, the gas composed of these electrons and positive ions (we call it plasma) will produce an upward electric field along the direction of the earth's magnetic field line, so the electrons in the plasma are accelerated by this electric field and enter the ionosphere at high latitudes, so only the charged particles that shoot to the polar regions can enter the upper atmosphere to produce auroras.

3. The geomagnetic north is in Canada (the geomagnetic north is about 1200km away from the geographical north pole. The two are intersected by the center of the earth. Auroras are common in southern Canada and the northern United States, and are rarely seen at low magnetic latitudes in Siberia.

The Northern Lights can usually only be seen at higher magnetic latitudes, but can be seen at slightly lower magnetic latitudes when solar storms are intense.

Scientists have been able to correctly ** the 11-year cycle of solar storms, a large number of charged particles from the solar storm rush to the earth, and interact with the geomagnetic field to produce the gorgeous scenery of the Northern Lights. The second millennium AD coincided with the peak of the 11-year cycle, which can also be seen in slightly lower magnetic latitudes.

4. The one located at the North Pole is called the Northern Lights, and the one located at the South Pole is called the South Lights, just like the halo on the head of an angel, set in the night sky of the north and south poles of the earth. The Northern Lights and Southern Lights can sometimes appear in pairs like images in a mirror.
