How Moon was formed? And is it full of Life?

Scientific society has been puzzled by the origins of the Moon for a long time. Any theory that was put forward had significant drawbacks. Now scientists came with the new one. The new theory solves one of the most persistent problems concerning the formation of the moon.

American and Japanese researchers in a new study come up with a surprising theory.

It is widely believed that about 4.4 billion years ago – about 150 million years after the formation of the solar system – a planet the size of Mars, called Theia, collided with the young Earth. However, this theory has been challenged in recent years. Computer simulations showed that if this theory is correct, the moon should mainly consist of material from the impacting object. Yet the opposite is true: samples of rocks brought back by Apollo missions show that the moon consists of earthly material.

This is where the new theory comes with a possible solution for the problem.

“About 50 million years after the formation of our sun, the early Earth was covered with a sea of ​​hot magma,” says researcher Shun-ichiro Karato. “The colliding object, Theia, on the other hand, consisted of solid material.”

The researchers designed a computer model to test what effect this would have. And the model shows that after the collision the magma became hotter than the crust of Theia. After Theia collapsed the magma would have increased in volume and then ended up in orbit around the earth. And thus the moon was born.

Any of the collision theories does not explain where Theia has gone. That is not only mystery that surrounds the Moon. There is an scientific work that tests the probability of Moon as habitable planet. It is coined by Schulze-Makuch and Ian Crawford. It seems nearly unimaginable that Moon once was a home to the life.
