Is there a difference in the light of the stars in different weather? What is the reason?

In fact, if you look closely, you will find that the sky at cloudy night is different from that at sunny night. When the day is very clear, the stars will be brighter at night, but if it is rainy, the stars at night can hardly see the light.

First, the color of the star In fact, the color of the star is determined by its own temperature. The surface temperature of stars is different, so the color of light emitted will be different. When the temperature of a star reaches 1 1, 500 degrees, it will emit white light, when the temperature of the star reaches about 2600~3600 degrees, it will emit red light, and when the temperature of the star reaches about 25000 ~ 40000 degrees, it will emit blue light. The temperature on the surface of the sun is 6000 degrees, so it looks yellow. Because we are very far away from the stars, plus the refraction of the atmosphere, we can't see the colorful stars with the naked eye.

Second, the light of the stars Many people who like stars will choose to observe the stars in the sky with a telescope, so that the stars they see will be clearer, so they can see the colors of the stars. Although the size of the planet is small, it is relatively close, so the light emitted will not disturb the atmosphere, because it can be distinguished by the naked eye, so it looks like a flickering state. Many people used to judge the weather of the next day by the stars in the sky. There are many stars in the sky and countless glowing lights in the universe. These celestial bodies are billions of kilometers away from the earth, so light can only fall to the ground through the atmosphere and space, that is, the stars visible to our naked eyes.

Thirdly, due to the uneven density distribution, the flicker degree of stars is constantly changing. Sometimes the stars we see are flickering, and the density is relatively small at this time. We can observe the twinkling of stars. If the twinkling of the stars is not obvious, it may be sunny the next day. If the twinkling of the stars is very obvious, it means that the gas layer is not stable enough and may become rainy.
