In the bowels of the moon found the remains of the ancient planet Teija

In the bowels of the moon they found the remains of the ancient Theia – protoplanets, the collision of which with the Earth led to the appearance of the satellite. This was written by Science Alert with reference to a study by Eric Kano, a professor at the University of New Mexico.

According to the main hypothesis of the appearance of the moon, more than 4.5 billion years ago, a space object the size of Mars, the protoplanet of Teia, collided with the Earth. The impact energy melted this object, and a piece broke off the Earth, which later became the Moon.

However, until now, scientists have not been able to detect any traces of the dead planet. According to calculations, the Moon should be 90% composed of a substance similar to Earth, mixed with the soil that remained from Teija, however, analysis of the lunar soil shows that it is 100% identical to the earth.

Scientists from the University of New Mexico conducted a new analysis of the isotopic composition of the lunar soil – they studied small satellite samples obtained from different sites – from the bottom of the dark basalt seas, to tear-eyed eyes raised from the depths of long-dead volcanic processes.

It turned out that the soil from these sites has a different isotopic composition – the deeper the rock was formed, the more heavy oxygen isotopes it contains. This makes the difference between lunar soil and terrestrial large enough to suggest the appearance of the moon from another space object.

Judging by the number of heavy isotopes, Teia should have formed far enough from the Sun. Probably, not far from the Earth, it appeared as a result of a gravitational anomaly in its orbit.
