‘Significant fraction’ of Earth’s water is older even before the existence of solar system and the birth of Sun, Boffins claimed.
The study conducted by Boffins Ilsedore Cleeves, at the University of Michigan states that, ‘significant fraction’ of Earth’s water was created by 4.5bn years ago.
This study is published in the Science journal, revealing the thought that water might be discovered elsewhere in the universe. And, where there is water, there is life.
The study stated that some parts of the water originated in ocean, comets, as well as meteorites and on the moon, which actually predate the sun’s origin. There is just one option that it is formed in the cold, the interstellar cloud from which the sun itself created, Boffins stated.
Boffins Ilsedore Cleeves revealed about the planet forming disks around young stars. These disks act as a shield from galactic rays developed due to strong solar winds which drastically changing the chemistry happening within the disks. He further told that, it seems very difficult for the region present within the disks to synthesize new molecules. Cleeves wrote in an email to Discovery News stating that “This was actually an ‘aha’ minute for us. The only place these gases would have come from, without creating water, was the chemically rich interstellar gas from which the solar system formed.”
The study result has implications concerning search for life beyond Earth, as water appears to be necessary for life.
Cleeves added, “If the sun was formed through the conventional interstellar ices, including water, are expected to have common elements needed for the creation of all planetary systems that set a magnificent view on the prospect of other life in the universe.”
