The moon. The only natural satellite on Earth. We know that it has no atmosphere like the earth. Absolutely not. Adding the total mass of the moon's entire atmosphere is slightly less than 10 metric tons. If you think the amount is too much, you will be surprised to know an information. The lunar atmosphere is 100 billion times less than the Earth's atmospheric pressure (15 zeros after 1). The sun is also responsible for the presence of this little wind on the moon. Under the influence of solar wind, this gas is produced by hiding, accumulating and absorbing gases in the grooves of various substances on the surface of the moon.
According to an article published in the journal Nature Astronomy on January 31, 2016, some of the Earth's oxygen is also going to the moon under the influence of the same solar wind and this has probably been happening since the creation of the Earth's atmosphere. That was hundreds of millions of years ago.
Scientists have found that this happens almost every month. We know that the moon revolves around the earth in an elliptical orbit. During this orbit, the moon stays in the magnetosphere of the Earth's atmosphere for about five days. The importance of the magnetosphere behind the habitation of the earth is very high. This region protects the earth from harmful radiation coming from different parts of the sun and space. However, some of the processes operating in the interior of the earth have played a role in the creation of this region. The magnetic field of the magnetosphere is formed by the convection motion of molten iron in the deep outer center of the earth's surface.
The magnetosphere is 8 to 10 times the radius of the Earth on the side where the day is. However, in the absence of solar radiation on the side of the earth at night, it reaches far beyond the orbit of the moon. Up to a few hundred times the radius of the earth.
Sometimes the moon stays behind the earth, in the opposite direction from the sun, when it crosses this region. For that reason, at this time it is free from the direct flow of solar wind. But the flow of matter from the earth continues to go towards it. Scientists already know that some gases, including nitrogen, are moving toward the moon. However, this is the first time that oxygen is gone.
"From the data we have, it is clear that the Earth and the Moon were not created at the same time, and that the chemical processes of the two are in parallel," said Kentaro Terada, an astrophysicist at Osaka University in Japan.
The new information obtained could solve a long-standing mystery about the chemical composition of the moon rock. There is no magnetic field around the moon like the earth. As a result it is directly hit by high charged particles coming from the sun. As a result, it was previously thought that the samples collected from the moon's exposed surface would be similar to the chemical elements in the solar system. In 2008, samples of lunar rocks were tested and found to have higher oxygen levels than normal. In other words, there is another role of oxygen in the oxygen on the surface of the moon. This time he was found in Weser.
This information was collected from the Japanese spacecraft Selini (local name Kaguia). Between 2007 and 2009, the vehicle orbited the moon and landed on the moon. While in orbit, it discovers high-positively charged oxygen molecules in the Moon's atmosphere. The important thing is that the level of oxygen was not always the same. This chemical was seen in only 5 days out of 28 days of the lunar month. Later it was found out that during these 5 days the moon is on the opposite side of the earth from the sun. Gets protection through the Earth's magnetosphere. As I said before, the moon does not have its own magnetic field to survive the solar storm.
The shape of the earth's magnetic field is not round, but like a teardrop
As can be seen in the picture, the shape of the protective magnetic field is not round. Rather, it is like tears. This part faces the sun, with its long tail spread out opposite the earth. Its name is Magnetotail or Magnetic Tail. Everything in the magnetosphere is protected from the sun's radiation. But due to the push of radiation, some particles come out of the earth's atmosphere. Moves to an area called the plasma sheet of the magnetic tail. According to Terada, some of the oxygen that most likely came out took refuge in the moon, and some went into the interstellar world.
