The stars are bright at night. Why do stars shine?

I don't know if you still remember a song called "Little Star" sung when you were young-"Twinkling Star, the sky is full of caution". Hanging in the sky, shining like countless small eyes. "When I was a child, this little star song has always been loved by people. It seems that every little star can speak on a starry night. But it's not near. There's a question. Why are the stars twinkling in the sky?

First, the stars in the sky twinkle because of the atmosphere, eyes and starlight.

The stars in the sky will twinkle. In fact, scientifically speaking, it is caused by atmosphere, eyes and starlight.

Our earth is a sphere, and there are many atmospheres outside the earth, so there will be different temperatures and densities in the atmosphere. When the star light enters the grass roots, it will keep moving in the atmosphere and wind, and then enter our sight through a series of operations.

Because light has different refraction and scattering in the propagation process, the intensity of light presented at each point is different. Therefore, when it enters our eyes, there will be different points of light, which is how we see the stars flashing constantly.

Second, the stars don't twinkle.

Since we can see the light scattered by the heart, there is another question. Will the heart itself flash? The answer is no, because stars themselves don't give off light. We can see that the light transmitted by the star will eventually reach our eyes because it has been transmitting.

There are many stars in the sky, such as stars and planets. Generally speaking, perseverance will twinkle more than the stars in the solar system. Planets generally don't give off light. Planets shine because they reflect sunlight.

Although the stars, won't he give off real light? But the light they produce through various complicated actions is the brightest star in our hearts.

Stars don't have some good wishes in people's minds. If a person is a good person, then after his death, he will become a star in the sky, constantly shining on his beloved. Although this is not true, good thoughts will have good karma.

Third, the degree of starlight shining is different in different weather.

We see stars shining in different degrees in different weather. Due to the obstruction of substances in the atmosphere, stars can diffuse light in different places, so we can see many stars flashing on sunny days, but rarely on cloudy days.
