Experts Study A Potential New Provenience Of Earth’s Water


New potential sources of our Earth’s water are currently being analyzed.

Earth’s water may come from asteroidal material and gas left over from the Sun’s formation, says the latest research, as reported by Science Daily.

This new finding could offer scientists some fundamental insights into the development of other planets and their potential to support life.

In a new study in the Journal of Geophysical Research: Planets, a journal of the American Geophysical Union, researchers are now proposing a brand new theory to address the mystery of where Eart’s water came from and how it managed to get here.

Identifying water sources on Earth

In order to identify sources of water here on Earth, experts have been searching for sources of hydrogen rather than oxygen because the latter component of water is more abundant in the solar system.

There have been a lot of scientists who have supported the theory that all the water from our planet came from asteroids due to the similarities between the water in the oceans and the one found on asteroids.

But, according to this recent study, our oceans may not be telling the entire story of Earth’s hydrogen.

“It’s a bit of a blind spot in the community,” said Steven Desch, a professor of astrophysics in the School of Earth and Space Exploration at Arizona State University in Tempe, Arizona, and co-author of the new study, led by Peter Buseck.

“When people measure the [deuterium-to-hydrogen] ratio in ocean water, and they see that it is pretty close to what we see in asteroids, it was always easy to believe it all came from asteroids.”

According to the latest research, several billion years ago large waterlogged asteroids have developed into planets while the solar nebula was still swirling around the sun.

“For every 100 molecules of Earth’s water, there are one or two coming from the solar nebula,” said Jun Wu, lead author of the study.
