The earth has three parts of water and some land, but scientists have still not been able to agree on a theory of how this water came.
A New Journal of Arizona State University researchers claims that the water on earth was formed by materials and gas brought by asteroids along with the gas over from the sun’s formation.
This study can tell a lot about how planets are formed and their potential to support life.
Most of the earth is covered with water, but we still do not know the origin of the water.
Researchers found that because comets contain a lot of ices, it could have delivered some water. Asteroids, which are not so watery but still rich, can also be a source.
Asteroids, which are the water source of the earth during the earliest days of its formation, is not a new concept. It has been demonstrated in earlier studies that water sources created early survival through all the heated rebuilding that the blue planet went through.
It is actually the simplest explanation that chemical signatures found in the earth’s water are the same as found in the waters of asteroids .
The hydrogen contained in the earth’s water, however, is not exactly the same type of hydrogen found in other parts of the earth ̵
1; especially near the source. This indicates that asteroids probably were not the only source.
“But there is another way of thinking about water sources in the formative days of the solar system,” said Peter Buseck, professor at the State University of Arizona.
“Since water is hydrogen plus oxygen, and oxygen is rich, any hydrogen source could have served as the water of the earth,” added Buseck.
The earth went through many rapid changes at the time of its formation.
The study challenges generally accepted thoughts about hydrogen in the earth’s water by suggesting that the element was partly derived from vacuum and gas remaining after the sun’s formation – called the solar needle.
If the abundant hydrogen in the nebula could combine with the rocky material of the earth as it was formed, it could be the ultimate source of the global ocean of the Earth, scientists said.
This is supported by new research that states that sunbathing may have existed with growing planets that would give hydrogen the chance to incorporate into the deepest parts of the planets.
“The sunset has received the least attention among existing theories, although it was the dominant reservoir of hydrogen in our early solar system,” says Jun Wu, an assistant research professor at varsity.
The new result fits into current theories of the formation of Sun and the planets. Instead of trying to explain the origin of all the world’s water with a single source, the study also takes into account several factors that may have caused such a major change .
It also has consequences for habitable planets beyond the solar system as this finds that even though planets are far from water-rich asteroids, they can still hold water. This in turn means that the design of habitable planets is not as much of an evolving process as predicted earlier.
The design of habitable planets is not similar a lot of a timely process predicted earlier.
Astronomers have discovered more than 3,800 planets that circle around other stars and many seem to be rocky bodies that do not differ very differently from ourselves.
The research group attempts to collect more data samples from the Earth’s mantle to support the new study and forward with laboratory experiments to understand the chemical processes in more detail as they may have occurred in the atmospheric conditions of the early earth.
