Why do the stars always blink and twinkle

It's the atmosphere that's playing tricks. We know that the atmosphere is not static, hot air is rising, cold air is coming down, and the wind is blowing around, and if you can put some color in the molecules of the air, you can see it up and down, colorful. This up-and-down atmosphere is also unevenly dense because it is turbulent.

Don't think that the atmosphere is absolutely transparent, its transparency is also determined by its density, just like glass. A piece of glass, if the density is uniform, the thickness is consistent, its light transmittance is very good, through it to see things will not be discounted, if it has different densities, this part is thick, that part is thin, through it to see things, it will produce an unreal impression. If we shake this piece of glass of poor quality again, then the impression will be even more blurred.

The reason why the stars blink is also here. It is this turbulent atmosphere that blocks us, as if it is like a piece of glass of bad quality that is constantly shaking, so that when we look at the stars, we always feel that the stars are shaking, like blinking our eyes. This layer of the earth's atmosphere, of course, cannot be missing, without which there is no life, but it is indeed an obstacle in astronomical observation, even in a well-equipped observatory, the huge optical astronomical telescope is still inevitably disturbed by it when observing celestial bodies.

Therefore, many observatories are located on extremely high mountains to avoid turbulent atmospheric disturbances. Even so, the problem has not been completely solved.

I'll start with the bad ones, "You've seen the stars blink and blink??? That's a deception in the story, okay! "But for comfort, I will tell you" for he saw his lover on earth, and he secretly sent him autumn waves, why the moon in heaven sometimes showed only half of its face, because he was shy, and I was sometimes like a star, and sometimes like the moon; Stars don't have eyes, they're big, hot balls of fire.

The light emitted from the stars has to pass through the Earth's atmosphere before it can reach our eyes. Because the temperature and density in the atmosphere are not exactly the same, and winds are formed, the atmosphere becomes erratic. In this way, the light of the stars is constantly blocked, sometimes in one direction and sometimes in the other direction, so that we feel that the light of the stars is constantly shaking, as if they are blinking.

1. Stars do not "blink", and the reason why stars "twinkle and shine" is related to the earth's atmosphere. The star in the universe is actually an ordinary star, and the stars in the universe will shine by themselves, and the stars will be the same.

2. The earth's atmosphere is divided into five layers, and the atmosphere is not moving, but shakes with the cold and hot changes of the air. When the light of the stars leaves the earth from the universe and is visible to our naked eyes, it needs to pass through the thick atmosphere of the earth, and the atmosphere is shaky, and the light of the stars is only visible to us after several refractions. It is because of this shaky atmosphere that the stars blink at us.

3. Starlight is a common phenomenon in nature. Light can propagate in a vacuum, and reeds can propagate in air, water, glass, and other media. In the same homogeneous medium, light travels in a straight line.

If the medium is not uniform, the direction of light propagation is deflected, and when the light is transmitted from the less dense part to the denser part, it is slightly deflected in the direction of the light as if the light enters water from air or other cut-offs, so the light is also refracted in the atmosphere.

Because of atmospheric turbulence, the light emitted by these star sources is refracted many times as it passes through the atmosphere.

1.The light takes a different route at different times, and the light that reaches our eyes at different times is not the same, and the stars seem to flicker and tremble, as if they are winking at us. In summary, it is due to the size of the star's ability to shine and the distance between the star and the people.

2.Blinking stars are called stars. The night sky was filled with countless bright stars.

If you look closely, you will see that there are stars that twinkle and shine, and some stars are bright but not shining. Shining stars are called stars, and these stars shine like the sun and look like blinking. And those stars that don't shine are called planets, which basically don't produce light and heat like the earth, and naturally don't blink.
