Why is the front of the moon completely different from the back side?

On Earth, humans see the moon always bright and immaculate. After years of exploration, scientists have discovered that there is another side to our moon. People on the earth can only see the front side of the moon and see the front side of the moon, but they will never be able to see the back side of the moon.

The front and back sides of the moon are very different, the front side of the moon looks immaculate, but the back side of the moon is black and not shiny at all, and the surface is pitted. Someone might be curiousWhy is the front and back sides of the Moon so different? In fact, it is mainly caused by the fact that the front and back sides of the moon face different objects and environments

1. The front and back of the moon are different for the reason that the front of the moon is facing the earth and the human beings on the earth, and the front of the moon has always been bright due to the irradiation of the sun. The far side of the moon is blocked by the sun's rays, which makes the far side of the moon look very dark. In addition, the far side of the moon is often hit by some meteorites in the universe, resulting in craters on the far side of the moon.

In addition, the cratering phenomenon on the far side of the moon is also related to the tides that occur between the moon and the earth.

2. A brief description of the moonThe moon is often called the moon in folklore. It is a natural satellite of the Earth. When it comes to the moon, I believe most people are not unfamiliar with it at all.

In the clear night sky, as long as we look up, we can always see that the moon is emitting moonlight, shining on us as we move forward. People on Earth look at the moon in the sky and find that it changes regularly, and it changes with time as well as the climate. On the 15th day of each lunar month, the moon will look very round like a round ball.

And once the fifteenth day of each month has passed, the moon begins to slowly turn into a crescent shape.

3. ConclusionThe difference between the far side and the front of the moon is so great is mainly because of the different environments they face.

Because the front side of the Moon is always facing the Earth and is affected by the Earth, the front and back sides of the Moon are completely different.

In the process of formation, the moon is affected by gravity and rotation and revolution, so that the front and back sides are not exactly the same, and the earth is actually the same, which is also full of potholes.

Because the Moon is an opaque sphere, one can only see one side of it. So it looks like it's completely different on the front and back.

Moon. The main difference between the front and back is the difference in the area of the lunar sea and the amount of impact. The characteristics of the two hemispheres are markedly different, with many huge lunar seas on the front (this is a cognitive error of early astronomers who thought that these plains had water, so they called them seas); The other side was hit and there were dense craters, only a small amount, and about the area was covered by the sea, compared to the sea on the front.

The most likely explanation for this discrepancy is that heat generation is concentrated in the frontal hemisphere, as has been confirmed by rays from lunar prospectors.

eruptions, but none of this explains why the South Pole-Aitoken Basin (with the lowest altitude and thin crust on the Moon) does not have as much volcanic activity as the storm ocean in front of it.

It is reflected in the material composition, morphology and structure, rock age, etc.

Why is there no "face" on the far side of the Moon?

In 1959, the Soviet spacecraft Luna-3 showed the world images of the far side of the moon for the first time. At that time, astronomers wondered about the high ground on the far side of the moon. No one can explain why the far side of the Moon is so different from the side facing the Earth.

The far side of the moon is covered with craters. Compared to the Earth-facing side, there are no dark spots on the far side of the moon (these dark spots are formed by large areas of basalt). It is precisely because of these dark spots that the "human face" on the surface of the moon is created.

Astrophysicists at Penn State believe they've solved the puzzle. The absence of dark spots on the far side of the Moon proves the presence of a thick layer of deposits of aluminum and calcium on the far side of the Moon.

One theory suggests that in the early days of the Earth's formation, a planet the size of Mars hit the Earth. This time the impactor was ejected into space and eventually formed the Moon. The tidal action between the Earth and the Moon is such that it is always the same side of the Moon facing the blazing Earth.

As a result, the Earth-facing side of the Moon always remains hot, while the far side cools down. This creates a thick crust on the far side of the Moon.

These astrophysicists at Penn State also believe that it is this hard crust that prevents the basalt magma from flowing out of the surface. When meteors hit the Moon, they are able to break through the surface of the side facing the Earth, causing magma to flow out, which forms the dark spots that make up the "face".

But researchers at the Massachusetts Institute of Technology have drawn new conclusions from new information provided by NASA's "Holy Grail" program. They believe that the "face" on the moon may have been caused by magma inside the moon, rather than by an asteroid impact. However, these researchers are not sure how these magmas are produced.
