The Earth has three parts of water and a piece of earth – even so, scientists have still not been able to agree totally on a theory as to the creation of this water.
A new paper from University of the State of Arizona The researchers say that water on Earth is made up of materials and gases brought by asteroids and gases from the formation of the sun.
This study can tell us a lot about planet formation and their life potential.
Most of the Earth is covered with water but we still do not know the origin of the water.
The water of asteroids and comet ice are not the only possible sources of water
The researchers noted that comets containing a lot of ice, they could have provided water. Asteroids, which are not so rich in water, but nevertheless abundant, could also be a source.
Asteroids being the water source of the Earth during the very first days of its formation, it is not a new concept. Previous studies have shown that water sources created early could have survived all the heated reworking that the blue planet had undergone.
In fact, this is the easiest explanation because the The chemical signatures found in the water of the Earth are the same as those found in asteroid water..
However, hydrogen in the Earth's water is not exactly the same type of hydrogen found in other parts of the Earth, especially near its source. This suggests that asteroids were probably not the only source.
"But there is another way of thinking about water sources in the days of solar system training," said Peter Buseck, a professor at Arizona State University.
"Because water is hydrogen plus oxygen and oxygen is abundant, any source of hydrogen could have been at the origin of it. water of the Earth, "added Buseck.
The Earth has undergone many rapid changes at the time of its formation.
So where does the hydrogen-producing water from the Earth come from?
The study questions widely accepted ideas about hydrogen in the Earth's water by suggesting that the element came partly from clouds of dust and gas remaining after the Sun formation, called solar nebula.
If the amounts of hydrogen contained in the nebula could combine with the rocky materials of the Earth during its formation, this could be the ultimate origin of the Earth's global ocean, the researchers said. .
This is corroborated by recent research that solar gas from the nebula could have coexisted with growing planets, which would give hydrogen an opportunity to integrate it into the deepest parts of the nebula. of the planet.
"The solar nebula has received the least attention among the existing theories, although it is the predominant reservoir of hydrogen in our early solar system," said lead author Jun Wu, assistant professor at the university.
How can this new study help us better understand the birth of planets?
This new discovery fits perfectly into the current theories about the formation of Sun and planets. Instead of attempting to explain the origin of all of the Earth's water from a single source, the study also takes into account multiple factors that could have caused such a change.
This also has implications for habitable planets beyond the solar system, as this finding indicates that even if the planets are far away from the water-rich asteroids, they could still retain water. This in turn means that the formation of habitable planets is not as tedious as expected.
The formation of habitable planets is not as tedious as expected.
Astronomers have discovered more than 3,800 planets orbiting other stars, and many seem to be rocky bodies not very different from ours.
The research team is try to collect more data samples from the Earth's mantle support the new study and continue laboratory experiments to better understand the chemical processes, as they could have occurred under existing atmospheric conditions at the beginning of the Earth.
