No, it's just because there's an atmosphere in between, the air is moving, and the light is intermittent, so you see him flashing again.
-
No. But there are exceptions, there are some stars that do change in luminosity, such as novae, supernovae, and variable stars, whose brightness changes over time, the first two are short-term abrupt changes, and variable stars are periodically brighter and darker.
-
You pig is the atmosphere, pull you out of the atmosphere, the stars will not flash.
-
You're just 100,000 why isn't it good to have time to learn more knowledge, and you don't do anything serious when you go online all day.
-
It has to do with a lot of things, like the movement of air, the refraction of light, and the blinking of your cute little eyes.
-
No, you see a twinkle because the density of the atmosphere is different, it is refracted in different places, and it looks like a twinkle.
-
The stars we see in the sky are actually shining all the time, and the stars "flash" because of the atmosphere around the earth.
There is a layer of atmosphere on the periphery of the earth, just like the water in a pool, when the light of the stars shines on the earth, when it passes through the atmosphere, it will be affected by the density and thickness of the atmosphere, and the atmosphere is not absolutely transparent, its transparency will change according to the different densities, when the light is disturbed by various different gases in the atmosphere, it will be blurred and shaken like looking at the coins in the pool, and we look like stars twinkling and twinkling.
Starry sky.
-
The stars we see in the sky are actually the reflected light of the planets, or self-emitting tubes. So because it's far away from the earth, there must be some occlusion or movement in the middle. So the stars we see will twinkle and twinkle.

Stars twinkle: caused by the atmosphere around the Earth.
The atmosphere around the Earth is very thick, and the degree of density varies from place to place, the closer to the ground it is, the denser it is, and the higher it is at altitude, the thinner it becomes. In addition, the atmosphere is not static, hot air rises, cold air falls, and there is always a flow of air, which makes the density of the atmosphere change from place to place.
Light travels in a straight line, but when light travels from one substance to another with different densities, its propagation direction changes, that is, the path taken by light will be deflected, this phenomenon is called refraction of light, which is caused by the propagation of light in two substances of different densities, water and air.
When light from a star passes through the atmosphere, it is also refracted due to the different density of the atmosphere at different altitudes. At the same time, because the density of the atmosphere is constantly changing in various places, the direction of starlight deflection is not fixed, but constantly changing.
When stars far away from the Earth pass through the high-altitude atmosphere, they are refracted by atmospheres of different densities and temperatures, and the starlight gathers and scatters for a while.

It is said that our deceased relatives are watching us.

Stars don't flash, we see stars with the naked eye because of the flow of the Earth's atmosphere.
A star that is close to people has a strong ability to shine in front of it, so people will shine brightly when they see it. However, even if a star is quite capable of emitting light, if it is very far away, it may not be as bright as a star that is tens of thousands of times less capable of emitting light.
The brighter the star, the smaller the magnitude. One of the most common magnitude systems is the U (ultraviolet), b (blue), and V (yellow) trichromatic systems (see "class=link> photometric systems) with absolute visual magnitude m=+, chromatic indices b-v=, u-b=. The color temperature can be determined by the color index.

Why do the stars twinkle and twinkle?
-
The stars in the sky do not shine, but are just an illusion created by the movement of the air currents in the eyes.
-
You won't pay attention to it if you don't flash it.
You see the stars twinkle and twinkle.
How many people have noticed.
-
Because there are a lot of flowing objects between the Earth and the stars you see, the reflection of the sun's rays on these objects will make you feel like the stars are shining.
-
They should absorb the daytime sunlight, and if the sun is stronger, the more it will shine at night.
Countless ones, 6974 are visible to the naked eye.
There are as many stars as there is in the universe. The universe is infinite, so there are countless stars. The shining stars in the sky, like the sun, are just the reason for the distance. 6,974 stars are visible to the naked eye. >>>More
Is it a popular science problem? If you look at it with the naked eye, you can see more than 6,000 of them, but half of them are in the other hemisphere, so you can see about 3,000 of them with the naked eye at night. >>>More
There are more than 6,000 stars in the sky seen by the naked eye throughout the day, and they are all stars except for the five major planets in the solar system, meteors, and comets. They are called "stars" because of their relative positions to each other, which are not visible to the naked eye for a long time. Actually, they are all moving, but they are very, very far away from us, and they are imperceptible to the naked eye. >>>More
Will celebrities cherish their fans? I think before the star is completely famous. Especially for celebrities below the third line, they will cherish each of their fans, because they can promote themselves, but they are not really grateful to them, just like they also hope to have a large number of fans, because these fans can ** their own articles, so as to make money for themselves. >>>More
Yes, as long as you are honest with each other, because feelings are managed by two people, as long as you are tolerant and trusting, you can absolutely can! >>>More
