Earth has three parts water and one part land – even so,
A new paper by Arizona State University researchers states that the water has been formed by gas.
This study can tell a lot about how planets are formed and their potential to support life.
Most of Earth is covered in water but we still do not know the origin of water for sure.
Asteroid water and comet ice are not the only possible water sources
Researchers noted that since they contain a lot of ices, it could have supplied some water. Asteroids, which are not as water-rich yet still plentiful, could be a source as well.
Asteroids being Earth's water source during the earliest days. It has been proven in previous studies that have been survived through the heated remodeling the blue planet went through.
In fact this is the easiest explanation as the chemical signatures found in the water on asteroids.
However, the hydrogen found in other parts of the Earth – especially near its source. This suggest that asteroids were probably not the only source.
"But there's another way to think about solar system's formative days," said Peter Buseck, Professor at the Arizona State University.
"Because water is hydrogen plus oxygen, and oxygen is abundant, any source of hydrogen could have served as the origin of Earth's water," Buseck added.
Earth went through many rapid changes at the time of its formation.
So, where did Earth's water-making hydrogen come from?
The study challenges widely-accepted ideas about hydrogen in Earth's water.
If the abundant hydrogen in the nebula could with Earth's global material, the researchers said.
This is supported by recent research which states that solar energy could be co-existed with growing planets which would give hydrogen the chance to be incorporated into the deepest parts of the planets.
"Said lead author Jun Wu, an assistant research professor at the varsity," said the lead nebula has been given the least attention among the existing theories, although he was the predominant reservoir of hydrogen in our early solar system.
How can we better understand the birth of planets?
The new finding fits neatly into current theories of how Sun and the planets formed. A single source, the study also takes into account multiple factors that could have caused such a big change.
It also has implications for habitable planets beyond the solar system as well as planets to get away from water-rich asteroids, they could still hold water. This is a process that can be done as a process of predictability.
The formation of habitable planets is not as much of a time-taking process as predicted before.
