4 questions about the moon .. NASA has never been able to answer

NASA has sent several flights to the Moon, the closest space object to the Earth, including manned flights involving 12 astronauts.

But despite these trips and many sightings of the moon, there are four mysterious things on the moon that NASA has not been able to unravel or explain.

What is the origin of the moon?

Since NASA and other international space agencies have begun to study the moon, they have not yet been able to determine the moon or its origin, although it appears to have come from the collision of space objects.

Many scientists agree that a space-sized space object struck the planet 4.5 billion years ago, which caused large amounts of rocks and debris.

These rocks and debris continued to circulate around the Earth and gradually merged to form a single space object, the Moon.

However, the emergence of a number of moon-sized debris means that the collision was so great that it would pull the Earth out of its orbit.

In any case, the idea of ​​collision may be present, but the question remains "what touched the ground and with what force?"

How did the water disappear?

Second, NASA found water on the moon in 2009 in the form of ice trapped beneath its surface.

However, scientists have not yet been able to provide an accurate and correct explanation of how water has reached it.

Some scientists believe that there was a period during which the Earth and the Moon were hit by a large number of meteors and meteors, some of which had to bring this ice to the surface of the Moon and this who had fallen on Earth must have melted into the oceans.

However, a recent badysis of the rocks brought by the Apollo 15 and Apollo 17 satellite missions revealed that the chemical composition of the rocks indicates that the water is buried deep in the inner layer of the moon and that it has reached the surface as a result of volcanic eruptions.

This means that water or ice on the Moon has existed for a long time, but is not limited to a collision between celestial bodies.

What do frozen craters hide?

There is no time on the moon or in the atmosphere, so the temperature during the day, when the sun falls on the moon, can reach 127 degrees Celsius and fall at night below 173 degrees Celsius Celsius below zero.

This means that all that is exposed to the sun during the day will be boiled by the heat and that any spot of constantly shaded sun will be able to constitute a refuge for the lunar ice.

Scientists have found many of these frozen craters or "cold traps" on the hidden or hidden side of the moon, which astronomical observatories can not detect or see.

Scientists still do not know what is hidden by these very cold areas, but it may contain frozen water and evidence that may contain the beginnings of the moon.

The Chinese probe "Chang 4", which landed Thursday on the dark side of the moon, is expected to explore the chemical components of cold traps, such as those known as "von Carman".

Is there life on the moon?

This is a big question that scientists face when studying the moon, according to The Sun newspaper.

Some scientists believe that there is water below the surface and that this water may contain extreme microbes in the foot because among the theories about the emergence of life on Earth, they have started with the microbes brought by the meteorites.

Professor Christopher Palma, professor of astronomy at the University of Pennsylvania, thinks that microbes may be present in the ice on the moon, but scientists will surely be there only after studying the surface of the moon and conducting extensive exploration and prospecting.
