Earth’s moon has had an ocean of magma for 200 million years … know the details


A new study concluded that the Earth’s moon may have possessed an ocean of magma for 200 million years, which is much longer than scientists previously believed, and scientists said that these new results may shed light on the formation of the Earth and the rest of the solar system, according to Russia today.

Scientists believe that the Earth originated about 4.5 billion years ago, when the Moon was born shortly after that. The main explanation for the origin of the moon is that it resulted from the collision of two primary planets, or embryonic worlds, one of which was the nascent Earth, and the other was a Mars-sized body called thea.

One of the important results of this scenario is that the early moon, which accumulated from the debris of this giant effect, was very hot, that is, hot enough to make the rock mantle largely molten and form what we call the vicinity of magma, according to the main author of the study, Maxim Morris, a planetary scientist in German Space Center Berlin, speaking to

Morris explained that previous research found evidence of such magma on the early moon in the formation of the lunar crust, which could be better explained as floating remains of molten rock that crystallized in lunar conditions.

Morris said: “While the idea of ​​an ocean of primitive magma on the moon is largely acceptable, the time it takes for solidification was not very clear.” He added: “Previous models indicated that it was fairly rapid, some tens of millions of years ago.” “.

Morris pointed out in the new study, that scientists have developed a model for the solidification of the vicinity of the ancient Lunar magma “which takes into account the impact of many of the processes that occurred at that time, some of which have been ignored until now”, and one of these processes is the thermal load of the jacket, the method by which That swirls formed and turned into molten rocks, which on Earth cause volcanoes. ”

In general, they found that the lunar magma may have frozen over 150 million to 200 million years, that is, it lasted about 10 times longer than previously thought, and Morris said they also estimated that the moon formed between 4.4 billion and 4.45 billion years ago, that is, after 50 1 million to 100 million years earlier than previously thought, and this age closely matches the era of the Earth’s nucleus.

“There is a strong connection between the moon formation event and the formation of the Earth’s nucleus, because the giant effect is likely to lead to widespread melting of the Earth’s mantle, which has greatly helped the formation of the nucleus,” Morris said.

If the moon was old according to the estimates of the new model, this indicates that the age of giant collisions such as the one that gave birth to the moon, which marked the last stage of the formation of the planets, remained active about 150 million years after the birth of the solar system, and Morris continued: “It was exciting It is extremely important to see that our findings have wide-ranging effects from species. ”
