On the moon, the water was always

Traces of moisture found in the structure of the lunar rocks, evidence against the theory of the Moon's formation as a result of the collision of large celestial body with the Earth.

The study of ancient lunar rock samples obtained during the program "Apollo", showed the presence of their crystal structure traces of water. This is not consistent with the theory of the origin of the moon glowing "garbage", which resulted from the collision of Earth with a large cosmic body Yusyue said Zhang of the University of Michigan (USA), one of the authors of the study. In this case, the high temperatures would not leave a trace of moisture, but the study of samples from the Moon show: the water was there from ancient times.

Using infrared Fourier spectroscopy, the researchers discovered the presence of hydroxyl (6 parts per million) in plagioclase grains that make up the lunar anorthosite. It is believed that anorthosites formed when plagioclase crystallized and floated to the surface of the ocean of molten magma. The presence of traces of water in them — hydroxyl — could mean that the lunar magma solidified much longer than expected "dry" scenario giant impact, said Zhang.
