Researchers from the University of New Mexico are certain that the bowels of our satellite hide evidence of an ancient collision that once radically influenced the development of our planet and could even cause the origin of life. About 4.5 billion years ago, something the size of Mars collided with a very young Earth, according to lifescience.com. The collision with the planet led to an unexpected effect: the mysterious object not only melted into the earth, but also broke off a large part of it, which later became the moon.
Discovered the remains of an old planet
The giant collision hypothesis that spawned the moon is one of the most interesting theories about the origin of the planets in the solar system. Despite the plausibility of the idea, scientists have long had no evidence that our night lamp can really only be a fragment of the old earth that occurred as a result of an enchanting cosmic catastrophe. Be that as it may, it seems that humanity has finally the first clues to an ancient collision hiding just below the surface of our satellite.

Theia, a planet that died at the beginning of the formation of the solar system, has long been one of the most popular models for explaining the formation of the moon. This model was able to take into account recent observations of samples returned from Apollo missions that contained extremely low levels of moon iron in the moon compared to Earth. In addition, oxygen isotopes in lunar samples collected by Apollo astronauts were very similar to terrestrial isotopes of matter and were very different from the composition of the oxygen particles on other objects in the solar system.
After analyzing the lunar samples collected in the highlands of the satellite, planetologist Eric Kano and his colleagues discovered what nobody expected: the isotopic composition of oxygen varied depending on the type of rock examined. In addition, the depth of the isotopes became much heavier than on the surface, which could indicate that a piece of old Teija in the satellite's gut remains intact.

Despite the fact that Teia once crashed to Earth, the old planet was most likely closer to the outer part of the solar system, but for some reason it migrated from the sun near the third planet. Teia was unable to cope with the attraction of a larger earth and fell on our planet. However, due to the homogenization at the time of a planetary catastrophe, the oxygen isotope composition was not completely lost and has remained almost in its original state until today.
Due to the fact that the last manned human expedition to the moon was carried out in 1972, the precious lunar rocks that scientists need to confirm Teija's theory are severely limited, which significantly reduces the speed of the research required. Even so, scientists promise that in the next few years we will finally see how the astronaut crews will make the long-awaited return to the lunar surface (unless, of course, the situation with corona virus and a currency collapse around the world will affect the speed of implementation) planned space programs). If such positive events occur for science, we can hope for a real boom in exploring the moon and its secrets – including further research into the hypothesis of a colossal influence that gave our planet the resources necessary for the origin of life.
