Why can you see stars on the earth, but they are black on the moon?

Who says you can't see stars on the moon?

You can see the stars on the earth, just like on the moon, and the stars are clearer on the moon than on the earth.

The reason why some people think that the sky seen on the moon is black is because they see the sky is black from some photos on the surface of the moon provided by Americans, and they don't see the stars all over the sky.

In fact, this is a simple photography problem:

Because the surface of the moon is not covered by dense atmosphere like the earth, and there is no dust and particles floating in the atmosphere to block and scatter sunlight, the reflected light on the surface of the moon is extremely strong when the sun shines, which causes a very strong light contrast between all objects on the surface of the moon irradiated by the sun and the sky.

Anyone with a little knowledge of photography knows that when the object you want to shoot has a strong contrast between light and dark, you need to control the shutter and aperture to avoid overexposure of a certain part, otherwise it will be a whiteboard.

Therefore, in order to shoot astronauts and landers clearly, the camera shooting on the surface of the moon needs to have a very high shutter speed. So the foreground is clear, and the sky as the background is underexposed and darkened. At this time, there will be no stars, including the earth.

The following photo of the astronaut and the earth is believed to be post-processed.

Of course, many people take this as a basis, saying that the pictures of Americans landing on the moon were taken on Hollywood studios, so there is no way to photograph stars.

From the point of view of observing stars, the moon is actually thousands of times larger than the earth, because its surface has no atmosphere, no dust, no clouds, and nothing that can interfere with light. Hubble telescope can see hundreds of millions of light-years away and take countless shocking photos of outer galaxies because it was launched at an altitude of 569 kilometers. The earth's atmosphere here is extremely thin, with no turbulence and light scattering, no ozone to absorb ultraviolet rays and no interference factors to light.

In fact, the surface of the moon also has conditions for observing deep space. It's just that the moon is too far away for human beings, which is inconvenient for equipment maintenance and data transmission. Maybe one day we can build a space exploration base on the moon and build a huge astronomical telescope to look up at the stars.

This question once involved an event that people talked about in succession, that is, questioning the authenticity of landing on the moon.

One of them is that the earth is blocked by the atmosphere and there are so bright stars in the sky. Why is there no starlight on the moon without any atmosphere? Many people faked shooting on the set, and landing on the moon was a complete scam.

As for whether the moon landing is true or not, I'm not here to defend it. However, there is no starry sky on the moon. I believe I can give you a good explanation.

Simply put, the reason why the earth has a blue day is entirely due to the scattering and blocking effect of the atmosphere on light. We know that sunlight is composed of seven colors, and the wavelengths of these seven colors are different. The wavelength of red light is the longest and that of violet light is the shortest. Generally speaking, red and yellow light have strong penetration ability and are not easy to scatter, while blue light is not only short, but also easy to scatter. When it is influenced by atmospheric molecules and sky water vapor, it scatters blue light to the whole sky, and the sky we see becomes blue. The sky has color, which is entirely the function of the atmosphere.

If the earth had no atmosphere, then we wouldn't have a sky. What we see directly is the dark space, and nature is as dark as the moon.

So the question is, what's wrong with not seeing the stars? I explained why the moon sky looks dark, and now I will explain why I can't see the starlight.

This is the best explanation. Can you see starlight on the earth during the day? Obviously not, the faint starlight is all submerged in the strong sunlight. Similarly, humans have only landed on the bright side of the moon. What's the bright side? But during the day, the stars are submerged in the sun, and the moon looks like night without atmosphere. The illusion that there are no stars at night is actually daytime.

In fact, what we see is the sky box, which is also commonly known as the sky environment ball.

In fact, scientists have long discovered that there is a mysterious protective layer outside the solar system. On earth, we can see the Milky Way with a telescope, and we can see the stars and the sea at night. However, after the spacecraft passed12 billion kilometers, this range was completely different. Standing in that range, a strange phenomenon happened: looking outside the solar system, it was dark. Except in the solar system, it is dark and the sun can't be seen, because sunlight can't reach12 billion kilometers.

This problem seems complicated from a scientific point of view, but in fact, people who have played games look very, very simple. Why?

Anyone who has done or understood the game production knows that there is something called an environmental ball. The starry sky you see when you stand on the earth is the environmental ball. There is a scope in the environmental field. Once out of that range, you can't see it.

Therefore, some friends may say, does it mean that the planet seen in the sky is fake? Actually, it's not. This planet really exists. However, even if there are more planets in your game world, you may not be able to see them on the earth, because your vision is limited and you can't see anything outside your vision.

Therefore, at this time, if an environmental protection ball is placed outside the earth, people can see the beautiful starry sky standing on the earth. However, every planet's environmental range has a range. You can't see it when you go out.

Some people may say that air, sunshine and so on, many factors. But in fact, the main reason is that the environmental sphere outside the moon is different from that on the earth. Just like when playing games, there are different environmental balls outside each planet.

In fact, the mysterious zone outside the solar system is equivalent to the vacuum zone inside the game. For example, if one planet is A and the other planet is B, an area without a model is an impassable dead zone. Generally speaking, it can only be spread through specific channels.

With the development of game technology, the virtual world is getting closer to reality. Many people find that one day, our virtual world will be 100% real.

Therefore, virtual model and virtual means are the best means to explain the mystery of the universe.

The landing point of human beings on the moon is usually on the front. When the moon revolves around the earth, it always faces the earth. Therefore, if the landing site is chosen on the back, it will affect the information transmission and reception between the earth and the lunar rover. Because the landing site is on the front, people see the dazzling sunlight reflected by the earth, or the sunlight shines directly on the front of the moon, which makes the distant stars reflect sunlight too weakly and look black. Just as we look at the sky during the day on earth, we can't see the stars. In fact, during the day, we look up at the sky and the stars are still there. On the moon, the situation is similar.

Can you see the stars when the sun is shining? Have the stars disappeared?

Because the earth has life, fresh air, high sky and smelly levels, the sky you see is blue sky and white clouds, your eyes can cross the line of sight, and the earth can be divided into days, so you can see the stars in the sky at night. As we all know, the moon goes around the earth, surpassing the sun forever, and there is no night. And the moon is different from the earth. There is no gravity, no atmosphere, and the line of sight cannot penetrate the sky, only darkness can be seen. There is no sunlight on the back of the sun, which is very secret. We will know the answer soon. On February 7th, 65438, the Chang 'e IV probe was launched and was about to land on the back of the moon. When will we know if there are stars in the sky behind the moon? We look forward to the successful launch of Chang 'e IV.

The stars are still those stars, the moon is still the moon. Standing at different heights, there will be different ideas, that's all.

Because there is no atmosphere on the moon. Without atmospheric scattering, the rays of the sun or the light reflected by the earth will cover up other light.

Shoot the sky with your mobile phone at night to see if you can catch the stars.

If you want to shoot stars, you need to adjust the parameters. Cell phones and cameras are the same.

The stars on the moon are brighter to the naked eye. The images we see taken on the moon are all made by optical instruments. Due to the influence of resolution, lens aperture and exposure time, we can't see the stars. Even on the earth, a camera without a large aperture can't shoot stars for a long time.
