Can t you see the stars on the moon?

In the night sky on Earth, as long as it is clear and there is no moon.

And without atmospheric and light pollution, we can see a sky full of stars, and we can also see a faint Milky Way. However, the sky photographed on the moon is all dark and no stars can be seen, why is that? Whether it's Apollo.

Astronauts, or Chang'e-3.

and Four, both of which are active during the daytime of the Moon. The reason why the moon's sky is dark during the day is because there is almost no atmosphere on the moon, almost no difference from space, sunlight.

It will hit the surface of the moon directly, and Rayleigh scattering will not occur as on Earth.

And make the sky blue. Therefore, even during the day on the Moon, the stars can be seen, they are not completely overwhelmed by the sun's rays, and only the area where the sun is located cannot see the stars. In this case, why is it that the sky in the moon** is so dark that no stars can be seen?

In fact, the Apollo astronauts who landed on the surface of the moon saw the stars, and the reason why there were no stars on the moon had to do with the camera. The surface of the moon becomes very bright under the sun's rays, and its brightness is much higher than that of the stars in the sky.

In order for the bright surface of the moon to work properly**, the amount of light entering the moon needs to be controlled, which makes it impossible to photograph the faint stars in the sky. If you want to photograph faint stars, you need to increase the amount of light entering the moon, which will make the moon surface too **, and you will not be able to photograph the normal brightness of the moon surface. Specifically, the following experiments can be used to make a simple verification.

The author uses an astronomical telescope with a focal length of 750 mm and an aperture of 150 mm.

With an eyepiece with a focal length of 25 mm (magnification of 30x), the Moon was photographed above. The moon is normal**, the surrounding sky is dark, and no stars can be seen. If you increase the amount of light, you can get the following scenes:

It can be seen that two stars have appeared around the moon, but the moon has passed by this time, and it is impossible to see its surface details. The largest and brightest object in the figure is the Earth, which has been **. And around the Earth, a lot of stars appeared, and they were all distant background stars.

You can see the starry sky on the moon because the moon is not blocked by the atmosphere, and when you look at the starry sky on the moon, you can see a lot of shining stars.

In fact, I personally think that you can still see the starry sky on the moon, because the moon and the earth are the same, they are both the same planet, but the location is different. There are also many planets that are far away from the moon, and from the moon, you can still see the starry sky.

The moon has no atmosphere, and the sky is dark during the day. The sun is as bright as an arc light, and you dare not look at it without wearing colored glasses. Since the moon has no atmosphere, you can see a starry sky no matter day or night.

No. There are countless planets in the sky, and the sun is only the closest star to us; The Moon is just the closest natural celestial body to us.

The stars we see at night, except for a few planets in the solar system, are all huge planets like the sun, and they are only small bright spots because they are too far away from us.

In the solar system, there are eight large planets, including the Earth, more than a dozen dwarf planets, hundreds of moons (the Moon is the natural satellite of the Earth), countless asteroids, and a larger number of interplanetary materials, such as comets, meteoroids, etc. The planets, dwarf planets, most moons, and a few asteroids are spherical and can be called "planets".

Outside the solar system, there are even more planets. All the stars we can see with the naked eye are planets, and all but the Moon and a few planets are stars in the Milky Way. The total number of stars in the Milky Way is no less than 200 billion, and it may exceed 400 billion.

Beyond the Milky Way, there are countless galaxies as huge as the Milky Way, ranging from tens of billions of stars to trillions of stars.

So, there are too many planets in the sky to count.

There are countless planets in the universe, and the stars you see are actually the same as the sun and the moon, they are all planets, but the stars you see with the naked eye are much smaller than the sun and the moon, but in fact they are not necessarily, because some are far away from the earth, so they will look very small.

Hello! Definitely not! In the Milky Way, there are planets such as Mercury, Venus, Earth, Mars, Jupiter, Saturn, etc. And the number of planets in the universe is a huge number, and the vastness of the universe is still waiting for human beings to explore!

The closest star to our solar system is the constellation Centauri, light years away. One light-year is equal to about a trillion kilometers, while the constellation Centauri is about 40 trillion kilometers from Earth. And then you fly another 380,000 kilometers to the moon to see it, which is 11 million distances, so it doesn't look any different.

All of this star provides the sun's light, but because of the position and size of each planet from the sun, the sun's light is different, there are strong and weak lights, if humans reflect the sun's light on the right side of the moon where the sun's light is strongest, then the moon will become a bright star, if you want to see the stars near the sun, you can't see it, because the moon is too bright, so if you look at the stars from the dim side of the moon, the stars will look brighter.

Why do we see stars on Earth but not on the Moon? Scientists explain that this is different from people on the earth, at night, look up and see the sky full of stars, that is because the earth is dark at the moment, which is why you can see stars on the earth, why you can't see stars on the moon, but look at the earth from the moon, the earth is also a star, if you want to see more stars on the moon, keep looking for the best commanding heights!

There is a special disease on earth called snow blindness. To put it simply, in a snowy environment, the reflection of the sun is very bright, making a person temporarily blind and requiring the wearing of special filters. Otherwise, snow blindness will appear quickly and it will take a few days to fully regain normal vision.

This means that astronauts' helmets must be specially designed to cope with the intensity of the sun, making it impossible to see such a dark star. Similarly, the camera used to record the crew's work must be fine-tuned for sensitivity or else it will be overdone and nothing will be captured. Hasselblad's film machine is used, it has to be adjusted.

It is used to photograph people and the surface of the moon, not the stars. So, of course, at the expense of the light in the dark area, of course, it is impossible to record such a faint star in a special environment.

Because it is reflected on the moon, its reflectivity is relatively high, and because of the atmospheric environment, the stars cannot be seen on the moon.

Because the stars we see on the earth are actually distant stars, which themselves will emit light, and our distance and position angle are appropriate, so we can see clearly, the position on the moon is facing away from the star, so we can't see it.

Because the atmosphere of the moon is different from that of the earth, there is nothing reflected in the atmosphere, so you can't see the stars.
