In the photos of the American manned moon landing, why is the background all black, and where have the stars gone?

"Why are there no stars in the photos of the American moon landing, and the space is so dark, isn't there a light source in space?"

This is a question asked by an elementary school student to the teacher, looking at the textbook in the photo of the American astronaut landing on the moon with only a single planet, no other stars, and it seems that the background of space is also relatively dark, he can't help but forget to confirm it.

This question also became a question to explain why the American astronaut star did not appear in the moon landing photo.

So why are there no stars in the photos of the American moon landing, and why is space so dark?

1. The reason why there are no stars in the photo.

In 1969, when man landed on the moon for the first time, then US President Richard Nixon invited outstanding people and scientific and technological experts from all over the United States and foreign countries to participate in a celebratory banquet with the theme of "developing human exploration of the universe".

The banquet was a great success, and after the banquet, Nixon presented the guests with a photo of the American astronauts on the moon as a souvenir to the guests who had attended the moon landing celebration.

In the background of this photograph is a photograph taken by an American astronaut during his journey to the moon, which is heavily shadowed, and is composed of the figure of the American astronaut on the moon and the coastline of Florida, USA.

However, many people are suspicious after seeing this photo, that is, this photo of an American astronaut in the background of space, since it was taken in space, why can't you see the stars in the background of the photo, and the space is very dark?

They also don't understand why American astronauts can go to space to take a picture of the United States behind them, and space is indeed a dark background.

But they think that space is very dark, and most places in space can refer to the night sky, so why can't they see the stars?

Some netizens said, "The background of the space photo is so dark, it must be that NASA knows that there are aliens in space, so it deliberately deleted the aliens in the photo in an attempt to cover up the secret."

Of course, this is just nonsense, after all, there is a saying in the first place, you can't just listen to one side of the story, just think so.

When the United States landed on the moon, it was indeed pitch black in space, but so what, space is like this, the space photos show that the background of space is indeed pitch black, and what I said above is correct.

After wrapping up this short episode, let's explore why the background of space is so dark.

An hour after the rocket departed, it entered the field of view of space, almost not obscured by clouds, but there was no atmosphere and no light in space, so space was indeed very, very dark.

But the curiosity is why can't you see a little light source in space?

Good question.

When the light hits the Earth's atmosphere, the sunlight will cause the oxygen atoms in the atmosphere to collide, and then it will form scattering in the air, and finally produce the light that hits the Earth in the background of space.

But there is no atmospheric scattering in space, so what you see is a dark space background.

Curious students may ask, "Is it because there is night on Earth and you can't see the stars because of scattering?"

It's a good question, if you look into space from the earth, you can see the starry sky, and this is the starry background.

If you take photos in the starry sky, you need to use a long exposure to shoot the night sky, but you must use a short exposure to take photos of the moon landing so that the bright light does not overexpose the moon landing photos.

Therefore, if you want to illuminate the moon landing site, you must use a short exposure method to take photos of the moon landing, but the sunlight not only illuminates the moon landing site, but also illuminates the stars, so it is everything to look at with the naked eye, but the camera shooting is different, the camera will overexpose the moon landing photos, and the camera will not be able to shoot the stars in space.

So that's why the space background is pitch black in the U.S. moon landing photo.

2. Space looks tangible.

Although it is dark in space, space is transparent, and the air looks shapeless, but space looks tangible.

So the air is invisible, the disturbing air is invisible, but we still can't see it, so if it is used to take photos of space, will there be disadvantages that affect the photo effect?

The perturbation teacher will definitely say, "I can't see it, there's no air in space, so it's invisible."

Is there air in space, or is it still invisible?

There is neither atmosphere nor air in space, so it is not visible in space, but what is invisible is not disturbing the air, but the tiny particulate matter in the air, so even if it is invisible to the naked eye, the camera can capture the tiny particulate matter in the air.

It is not to blame that American astronauts will find that there are stars in space in the photos taken after landing on the moon, and they are not to cover up the presence of aliens in space, but for scientific exploration.

3. Why can't I see stars in the photos of the International Space Station and Tiangong Space Station?

The reason why the stars are not visible in the photos of the International Space Station and the Tiangong Space Station is the same, and it is also to photograph the light of the space in which they are located, so they also use the method of short burst exposure.

The two stations were photographed not only to photograph the light of the station they are in, but also to photograph the space station on the other.

Both stations are located on different space stations, so a phenomenon occurs that the stars seen at different times are different, sometimes more and sometimes less, so the exposure time will be too complicated when shooting.

So after the scientist finished shooting, he explained: "They shoot for scientific exploration, camera exposure, so for camera exposure, the purpose of taking photos is not to hide anything, and they are very affirmative: "When they take photos, of course, they have to consider the light in space space, so the camera is exposed, and the space station uses short burst exposure, so they can't see the stars in the space they are in."

epilogue

Space exploration is the trend of human development in the future, and after the American astronauts landed on the moon, there was a saying: "When you go to the moon, you find that there are no stars on the moon, and the sun's rays brightly illuminate the moon landing site."

Space exploration will bring many resources and opportunities to mankind, and may also promote the progress and development of human society.

When human beings explore space, they may also face many new challenges and problems, such as survival and adaptation in the space environment.

The entry of humans into space is the beginning of the space age, which may also make space lose some of its mystery, but at the same time there may be more scientific discoveries and technological breakthroughs.

Space is also the trend of human evolution in the future, so what can human beings develop into in space in the future, is it environmentally friendly and energy-saving?

As human beings continue to enter the era of space, some misunderstandings and questions will gradually be explained as human beings explore it, and people's understanding of space will become deeper and clearer.
