Stars always twinkle and twinkle, do you know it has something to do with the atmosphere?

Yes, it is related to the atmosphere, and some stars in the universe will flash and flash when they are in motion and the friction generated by the atmosphere.

It is related to the atmosphere, because the atmosphere is jitter, the stars themselves do not emit light, it is the light that reflects the sun, and these lights will be constantly refracted because of the jitter of the atmosphere, so the stars we see are twinkling and twinkling.

It has nothing to do with the atmosphere. Not all stars will flash, and the stars that will flash are also divided into two situations, one is the regular flash caused by their rotation, and the other is the irregular flash that appears when it is occluded

It is related, the stars we see are stars that will always shine, but due to the atmosphere, there is a time difference between the light of the stars and the earth, so they will twinkle and flash.

The star itself does not twinkle, but it seems to do, and that's because when looking at the star, the eye must look at the air that covers the earth. When the light of the star shines on the earth, it must pass through the uneven layer of air and different air layers, and different air layers reflect different starlight, so that the brightness of the star is changing, so the star is flashing.

When the light of the stars passes through the atmosphere of alternating hot and cold, the light source reflects different light sources in different air layers, so the stars are twinkling and twinkling when seen on the earth.

It itself does not flicker, and the vision has to pass through the air that covers the earth, and when the light of the stars hits the earth, it refracts the starlight through the unstable layers of cold and hot air, and various different layers of air refract the starlight in different forms.

Because of the Earth's atmosphere, the stars twinkle, and because starlight has to travel several kilometers through the atmosphere to reach the human eye, as common as we do from the bottom of the swimming pool ** universe. The Earth's atmosphere is turbulent, with air currents and whirlpools constantly forming, perturbing, and dissipating. Like lenses and prisms, these rheological properties slightly change the position of the starlight several times per second.

But for an object as large as the moon, these shifts will be balanced. On the contrary, the stars are far apart, like point light sources, so the starlight quickly shifts left and right, and the brightness flickers with it. As for planets like Mars, Venus, Jupiter that look bright.

They are closer to the Earth and look like a disc that can be measured from glasses. The scintillation produced by the edges of the disc will also be uniform, so the light emitted from these planets will not change much. Due to changes in the temperature of the Earth's atmosphere, cold air in the upper layers of the atmosphere sinks and warm air rises in the lower layers.

Cold air is dense and warm air is less dense. It's the wind. This thick layer of air, which varies in temperature and density from time to time, causes the light passing through it to be refracted repeatedly, causing the light emitted by the stars to travel back and forth on its way to our eyes.

Twinkling stars are visible to the naked eye due to the influence of the atmosphere. The principle is as follows: the stars seen with the naked eye are far away from us.

In the middle of this distance, there will be an atmosphere, which is actually blocked by some material. Although the atmosphere is transparent to the naked eye, it is not absolutely transparent. It has a certain density.

For example, at night in the countryside, the stars look transparent and bright, while at night in the city, they appear less transparent. Later, without light you can only see a lot of stars. Including the density and thickness of the atmosphere, transparency is affected by the increased resistance of light propagation, which makes the stars we see less bright.

With the movement of the atmosphere, the transparency of the atmosphere in different regions is different, so the transmittance of light is also different. Therefore, due to the blockage of the atmosphere caused by different brightness changes, we have Venus in our eyes. It's like the stars are twinkling.

The stars themselves did not twinkle.

There are two main factors that determine whether a star is observed to be light or dark: the star's ability to emit light; The strongest luminous ability is about 10 billion times worse than the worst luminous ability. the distance between the stars and people; Stars that are close to people have a great ability to glow, so people will see it glowing. However, even if a star has a considerable ability to emit light, if it is far away, its brightness may not be 10,000 times less than its luminous ability.

If not affected by external forces, all objects tend to converge towards the center under the action of gravity. The most concentrated result is a sphere. Although the surface of a star is solid, it may become spherical because the solid is deformed and the solid particles can move.

The stars appear to twinkle and twinkle, and that twinkle is due to the twinkle and shaky atmosphere itself. The atmosphere is flowing, and when the light of the stars reaches the atmosphere, the light will be refracted differently with the uneven flow of the atmosphere, so the stars you see will often twinkle and twinkle.

This is because these stars are inherently shiny, and when they hit the atmosphere of different thicknesses, the light will be refracted and the stars will twinkle and twinkle.

This is because the "stars" in space are not motionless, and the Earth is also rotating, so it will twinkle and twinkle depending on the angle.

Because the atmosphere is constantly moving, the density of each part of the atmosphere is completely different, so the direction of light changes as it propagates.

Because the stars we see are very far away from us, the stars also reflect the sun's rays, so the stars we see are twinkle and twinkle.

This is due to the atmosphere, which is why light changes when it enters the atmosphere.

The stars themselves are not spared, the reason why we can see the starlight is due to the atmosphere, the light is refracted in the atmosphere, so this is also the reason why the stars are not visible during the day, and there will be starlight at night.

Because we just see the light and shadow of hundreds of millions of years ago, and this light and shadow will make our human eyes look twinkle and twinkle, so the stars will have this phenomenon.

Let me give you a possibility: perhaps it is time for the star to enter the final stage of its life, and what we will see in its final bloom is countless light-years away.

The universe is so big, the sun is shining. Writer Yang Daxia Yang Ke described.

Preface: There will be many stars in the sky at night, but some careful people will find that the stars in the sky will also flash and twinkle, in fact, this is because the luminosity of the stars themselves has changed, and it also has a certain relationship with the occlusion of the atmosphere, because the stars are very far away from the earth, and there will be an atmospheric compartment in the middle of the stars with the naked eye, and the starlight will pass through the atmosphere, so it will be affected by the density and thickness of the atmosphere. Because the atmosphere is not absolutely transparent, it will change according to the different densities, so we will have stars twinkling and twinkling on the ground.

The stars in the sky are very far away from the earth, about a few light years away, we observe the stars on the earth with the naked eye are very small, but in fact, the volume of the stars is also very large, can emit strong light, if the stars are relatively close to the earth, the earth will be illuminated by the stars, it can be seen that the light of the stars is also relatively strong, but because the stars are several light years away from the earth, so it will look very small.

Because the stars are shining at the same time, the atmosphere in the earth will affect the brightness of the stars, the atmosphere in the earth is like clouds, and the atmosphere is not completely transparent, so if you stand in the perspective of the earth to ** the stars, they will be blocked by the atmosphere, thus covering the light of the stars. There is also wind in the atmosphere, although the wind at night is not felt by normal people, but these atmospheres will be affected by the wind and change, thus blocking the stars, and there will be a twinkle and twinkle.

The reason why the stars will flash and twinkle has a certain relationship with the atmospheric temperature on the earth, because the temperature on the earth is constantly changing, so the air in the atmosphere will also have a certain impact, if the density of cold air in the atmosphere is relatively large, it will produce wind, and the light will be refracted through the air layer, so the human eye will flicker in the process.

Because the stars are very far away from the earth, the light rays are refracted when they meet the atmosphere, so the light rays have different intensities, giving people the feeling of flashing and flashing.

Because the brightness of the stars themselves changes, there will also be brightness due to the occlusion of the atmosphere, so the stars are twinkling and twinkling.

The stars themselves don't twinkle, but why do the stars we see always twinkle and twinkle? If you look at the stars at night, you will notice that the stars often twinkle and dim. You might be wondering"Why do stars twinkle?

However, when you look at a star that is constantly shining, you may just find it shining quietly. Due to the interaction between your eyes, starlight, and the Earth's atmosphere, their brightness and dimness are different.

<> The temperature and density of the Earth's atmosphere vary with altitude. In addition to the difference in temperature and density, the air currents in the atmosphere are also inadmissible (we actually call it"Wind"）。When a star's light enters the Earth's atmosphere, it must pass through the atmosphere, which is constantly moving under the influence of wind, which is often referred to as turbulence in astronomical terms.

We always thought that the starlight we see travels in a straight line, but it is not. On the contrary, starlight is refracted or scattered in different directions in the atmosphere. When starlight moves towards the Earth, it is curved due to changes in the atmosphere.

When light is scattered or diffused, the brightness of the star changes, causing us to see the star"Flashing"。

The influence of the atmosphere on light causes us to see stars twinkling. However, you should know that the stars themselves do not twinkle. Just because the bending and diffusion of light makes you feel like it's flickering.

If the wind is strong or the temperature is high, the stars will twinkle more easily than on a calm night. The stars themselves glow; The planets themselves do not emit light, but they reflect sunlight. They can be observed when their light hits the human eye.

These stars are far away from the Earth, and the light emitted from them, transmitted to the Earth, can approximate parallel light. Biologists have discovered that moths use starlight to navigate, and as long as they maintain a certain angle to the starlight, they can fly in a straight line. But the advent of artificial light sources has disrupted the lives of moths.

Because most of the artificial light sources are divergent light sources, when the light moth is flying, it still maintains a certain angle of inclination with the light source, and the result is that it is getting closer and closer to the light source"Moths to the fire"phenomenon.

Do you know? Why do stars twinkle? Perhaps many people know the reason why the stars twinkle, but the reason why the stars twinkle at night has always attracted people.

Stars are celestial bodies in the universe that are visible to the naked eye, mainly divided into planets, stars, moons, white dwarfs, small bodies, etc. The irregular shape of a star is due to the energetic activity inside it. The brightness of a star is usually measured in terms of magnitude, and the brighter the star, the smaller the magnitude.

There are two main factors that determine whether a star is light or dark.

<> one is the ability of the star to emit light, and the other is the distance between the star and the person. The planet itself does not emit light, it is just sandwiched in the light that is very close to us, and what we see is that it reflects the sun's rays, so it appears brighter than the stars. A star is a large celestial body like the Sun that reacts internally to radiate energy into space in the form of light.

Comets, such as Halley's Comet, have long tails because the light we see is caused by the melt of the comet's material as it passes through the solar system. Most of the stars that can be seen at night are stars, but there are a few planets from our solar system, such as Venus, Mercury, and Mars. Stars emit light in a similar way to our sun, mostly from helium nuclei formed by the fusion of hydrogen and partly from helium fusion.

It's just that because they're so far away, they look like gentle little stars, but in reality they're much bigger than the sun.

In the night sky, there are nearly 6,000 stars visible to the naked eye, but if you look closely, not all of them will twinkle. The twinkling stars we see are usually stars. The closest star to Earth other than the Sun.

Reasons why stars look like twinklesStars are an integral part of the celestial system, stars twinkle while planets don't.

This fascinating phenomenon is the main reason why people love to look at the stars, but why do the stars twinkle? The light of the stars must penetrate the atmosphere before we can see the stars, and the atmosphere is flowing, and the light of the stars will produce different light with the unevenness of the air flow at the same time as the light of the stars reaches the atmosphere, and the influence of the temperature and density of the earth's atmosphere will cause the light to be refracted . Since the refractive effect of light is different every time, from people's perspectives, it seems that the light from the stars will appear in one location at the moment, and after a thousandth of a second, it will be refracted to another location, which is scientifically known as a flash, or astronomical flash.

Because the stars are very far away from our place, and the stars we see are only images left hundreds of millions of light years ago, sometimes we can see them, sometimes we can't see them, so they will twinkle and twinkle.
