Scientists have found that the Moon formed as a result of a frontal collision of the Earth with the planet Theia after about 100 million years after the formation of the globe. Previously it was thought that the collision of planets occurred on a tangent at an angle of 45 degrees.
In the latest study, published in the journal Science, analyzed seven rock samples brought to Earth from the Moon expedition Apollo 12, Apollo 15 and Apollo 17. They also studied the volcanic rocks of Arizona and Hawaii. As a result, the researchers found the oxygen isotopes in the samples from the satellite, which relates to a purely earthly.
We found no difference between isotopes in lunar and terrestrial rocks, – commented on the opening of Edward Young, author of the study. If the collision occurred on a tangent, the chemical composition of cosmic bodies would have been different, the majority of the Moon would be similar in composition to Teyey.
Scientists also plan to find out whether the kick effected the disappearance of water from some areas of the earth.
