NASA has sent several flights to the Moon, the closest spacecraft to the Earth, including manned flights involving 12 astronauts. Despite these flights and many sightings of the moon, there are four mysterious things on the moon. NASA has not been able to Uncertainty or interpretation.
What is the origin of the moon?
Since NASA and other international space agencies began studying the moon, they have not yet been able to determine the origin of the moon, even though its origin seems to have been caused by collisions 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 only one space object, the Moon.However, the appearance of a number of debris from the Moon size made the collision so significant that it would drive the Earth out of its orbit. But the question remains "what hit the ground and by any force"?
The arrival of water on the moon?
Second, NASA found water on the moon in 2009 in the form of ice trapped beneath its surface, but scientists have not yet been able to provide an accurate and correct explanation on how whose water has arrived there.
Some scientists think that there was a period when 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 what fell on Earth had to melt in the oceans.
A recent badysis of rocks brought to Earth by Apollo 15 and Apollo 17 revealed that the chemical composition of the rocks suggests that the water is buried deep in the inner layer of the moon and that it has reached the surface at following volcanic eruptions. The moon has existed for a long time, but beyond the idea of 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 everything that is exposed to the sun during the day will be boiled by the heat and any place in the shade of the sun may be a refuge for the lunar ice.
Scientists have found many of these frozen craters or "cold traps" on the other side of the moon or on the dark side that 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 the so-called "Vaughn" nozzle.
Is there life on the moon?
This is one of the big questions for scientists studying the moon, according to the British newspaper The Sun. Some scientists think that there is water under the surface and that this water can contain extreme microbes in the foot. Among the theories about the emergence of life on Earth, they started with microbes brought by meteorites.
Professor Christopher Palma, professor of astronomy at the University of Pennsylvania, thinks that these microbes may be present in the ice on the moon, but scientists will be certain that after having studied the surface of the moon and conducted extensive exploration and exploration work.
