NASA’s Apollo missions brought back the moon’s rock samples to the study of scientists. We have learned a lot in the coming decades, but there is a sustainable mystery. Many of these lunar samples show signs of displaying strong magnetic fields than the earth, yet the moon does not have such a field today. So, how did the moon’s stones find their magnetism?
Many attempts were made to explain this irregularities. Comes from the latest MIT scientists, who discuss A new paper The journal Science published that the effects of a major disciple promoted the first weak magnetic field of the moon – and that it was recorded in some of the growing lunar samples.
Evidence in addition to the observations of the spacecraft as well as the evidence The results were announced Earlier this year’s Chang 5 and from China Chang 6 The mission is widely compatible with the existence of at least a weak magnetic field on the early moon. But where did this field come from? They usually form the bodies of the planets as a result of a dinumo, in which the molten metals in the core begin to eliminate the heat by gradually eliminating the heat. The problem is that there was a mantle in the small core of the early moon that was not cool than its basic, so there was no special connection to produce a strong dinum.
The proposed assumptions are presented on how the moon can produce basic dinumo. For example, A 2022 analysis It was suggested that in the first billion years, when the moon was covered in a molten rock, the giant rocks were formed with the cool and stable. Denser minerals sank on the cover while light people formed a layer.
Over time, the authors argued, a titanium layer was made of crystal just below the surface, and because it was much less than light minerals, this layer eventually broke into small cloaks and sank through it (gravity overturned). The temperature difference between the cold sinking stones and the hot core was created, which created a strong magnetic sector from time to time.
Or perhaps the presence of a dinumo -powered magnetic field is not required. For example, authors The study of 2021 The first analysis of lunar samples can be changed during this process. They re -examined the 1972 Apollo 16 missions samples using CO2 Lasers refrain from doing any change in the magnetic carrier, thus making them warm. He concluded that any magnetic signatures in these samples could be explained by the effects of the moon or the effects of the dimension.
