What new substances were found in the lunar rock?
Scientists from Washington University conducted a study on the history of the formation of the Earth's satellite. To do this, they analyzed the composition of meteorites found in Antarctica.
There are several versions of the origin of the moon. The most popular one says that it was formed after a celestial body the size of Mars crashed into the young Earth 4.5 billion years ago. As a result of the collision, a stream of debris was ejected from the bowels of our planet, which subsequently combined in orbit, forming the Moon.
A group of scientists led by space chemist Patricia Will
strong>found another proof of this hypothesis. Using a mass spectrometer, the researchers analyzed the chemical composition of six lunar meteorites that were recovered from the ice of Antarctica. The fact is that during the time of the existence of the Moon, asteroids also crashed into it more than once, and fragments of these collisions regularly fell to Earth. They and were studied by experts.
The found meteorites consist of basalt, into which magma has turned. ejected from the bowels of the moon. After cooling, glass particles formed in it, retaining the chemical characteristics of gases. It turned out that these gases — helium and & nbsp; neon, which are of terrestrial origin. Theoretically, they could be brought to the Moon by the solar wind, but scientists have found that several layers of basalt covering the glass exclude any external influence on it. Thus, they conclude, the Moon “inherited” these chemical elements are from the bowels of the Earth.
A means they were once a single celestial body.
