Discover the Science and Spectacle Behind the Northern Lights

Posted on

Readers will be aware of the long streaks of light often seen above the skies of the world’s polar regions.

This natural beauty in the sky attracts tourists from all over the world, and it is also interesting from a scientific point of view. So let’s take a look today with ZeroKSL behind the orchestrated activities of this series of lights. . . .

The northern lights, called aurora, which move like young children in the sky, can be seen from the South Pole and the North Pole, as well as from space. The Northern Light still changes its name depending on the location where it is seen.

The Northern Hemisphere above the equator is called the Northern Light, and the Southern Hemisphere below the equator is called the Southern Light. It’s not that the term is this royal, but it’s the sun that is the main contributor to the creation of those light sequences that cause discomfort in the eyes.

The sun mainly provides heat and light energy to the earth, and the sun’s magnetic field contains a large amount of high-energy electromagnetic particles, and these electromagnetic particles can escape from the sun and reach outer space. These high-energy charged particles are roughly called solar wind. Solar wind waves are usually very small particle waves. 

The sun does not have a magnetic field, but the earth has its own magnetic field. The solar wind, which is released from the sun, is a wave of high-energy particles called the solar wind, which sometimes hits the Earth. But most of them are unable to enter the Earth’s atmosphere beyond the Earth’s magnetic field.

These small particles from the sun and the world’s magnetic field can be said to be the main protagonists that cause the Northern Lights called Aurora. So, how will these protagonists make Aurora a little girl? . . ?

Auroras are caused by the collision between these particles from the Sun and the Earth’s magnetic field. The sun does not always emit the same amount of energy. Sometimes a higher than normal amount of energy is released into space. In these conditions, high-energy charged particles, which are stronger than the solar wind, It released a lot of gamma rays and plasma.

This large amount of plasma released from the sun is called a solar storm.When solar storms occur, large explosions equivalent to hundreds of hydrogen bombs detonating on the sun’s surface are often preceded. It is through the stimulation of these explosions that solar storms occur. In some periods, billions of tons of plasma particles from the upper corona layer of the Sun, Once again, it emits large balls of high-energy gas that are often mixed with electromagnetic fields, including electrically charged particles. Such high-energy bursts from the Sun are called Coronal Mass Ejections (CMEs) (a variant of solar storms). When CMEs occur, plasma particles and other particles come into contact with Earth’s magnetic field.

At this time, the electromotive plasma waves deviated. But some wave edges that do not deviate enter the Earth’s poles. When these electrically charged particles arrive in the Earth’s atmosphere, they once again collide with gas particles in the atmosphere. Particles from the sun and particles from the Earth’s atmosphere collide like this, creating beautiful northern lights in the sky.

When electrically charged particles collide with oxygen particles in the air, a green (or red) yawn reaction occurs, and when they collide with nitrogen, a series of blue (or violet) yawns of light appear. Of all the planets, not only Earth has these auroras, but Jupiter and Saturn have similar auroras to Earth. Also, not only Jupiter and Saturn, but any planet with a magnetic field will see these lights in the polar regions. As long as the Earth has a magnetic field, The sun is the solar wind.

As long as CMEs and charged particles continue to be emitted, humans will continue to see these beautifully orchestrated aurora borealis movements in the polar regions. So, if you haven’t seen it yet, try to make it look the same with your loved one once in your life. . . Whether there is or not. .
