Studies show that moons and waters were created by collisions with Earth outside the solar system

It is unusual in the solar system that the earth is rich in water, and life has evolved thanks to this water. New research shows for the first time that the origin of water present on Earth is related to the origin of the moon, another axis that supports life on Earth. It is said that all were born from the fact that the celestial body that came from outside the solar system collided with the earth.

Formation of the moon brought water to Earth

There are multiple theories that explain how the moon, the Earth's satellite, was formed, and one of them is the giant, which says, 'The moon was formed as a result of a collision between a primitive Earth and a Martian-sized object.' There is an impact theory . In the giant impact theory, a virtual object that collides with the earth is called the thea, and it was previously considered 'thea is an astronomical object in the solar system.' In a new paper, I indicated that I came from outside the solar system.
On the other hand, another fact that makes the Earth the earth is that despite the existence in the 'dry' solar system, there is abundant water in the earth. Previous studies have shown that the solar system is composed of 'dry' substances that do not contain water. Since 'carbonaceous materials' containing a large amount of water and hydrocarbons are substances outside the solar system, it has been argued that it is the carbonaceous materials outside the solar system that brought water to the earth. On the other hand, it was not clear how and when carbonaceous matter came to the earth.

“To answer this question, we used molybdenum isotopes ,” Gerrit Budde, who did the study this time, “molybdenum isotopes make it possible to unambiguously distinguish between carbonaceous matter and non-carbonaceous matter, He says, 'It is the DNA of a substance,' which determines whether a substance is from outside the solar system or in the solar system.
Analysis showed that some of the molybdenum present on the earth originates outside the solar system. In addition, since the molybdenum present on the earth exists in the mantle located outside the core, researchers have concluded that molybdenum came from outside the solar system later in the Earth's formation. This is the first study to show that carbonaceous matter came from outside the solar system later in the Earth's formation.
Researchers also found that much of the molybdenum contained in the mantle came from the thia, which had collided with the Earth 4.4 billion years ago and made the moon. This means that Tear is also an astronomical object coming from outside the solar system. Scientists explained that this collision resulted in abundant water covering the entire earth. 'Our approach is unique in that it combines the formation of the moon with the origin of water for the first time. Simply put, life may not have been born on Earth without the moon,' said research.
