The incredible source of water on Earth

American scientists have found the origin of the first drops of water on Earth, which helps our planet become a place of life.

A study published in the journal Journal of Geophysical Research: Planets has just announced the first "water building blocks" for the young Earth. It is the Sun and asteroids, meteorites from distant places in space.

The young earth receives water from many celestial bodies, of which the biggest contribution is the solar nebula.

In particular, the sun contributed the most enthusiastically. Nearly 1 out of every 100 water molecules on the Earth's surface originate from the solar nebula - a great cloud of gas that produces the sun and exists around it like a giant cloud of dust throughout its early days. Solar system.

In addition, according to the research team led by assistant professor Jun Wu (School of Molecular Science and Earth Exploration School, Arizona State University, USA), the water that the sun originally " gave " to Earth remains. at an enormous amount of 7 underground oceans: 2 oceans in the mantle and 5 others in the core.

Water is formed by hydrogen and oxygen atoms and it is the solar nebula that provides the first hydrogen molecules. Scientists have confirmed this chemical mark by examining the ratios of hydrogen isotopes that exist on Earth. In addition, countless asteroids and meteors also participated in the process of providing these first "water building blocks " by . colliding with the Earth.

As a result, the Earth began to have water - an important premise for the emergence of life, in addition to stable trajectory in the habitat of and a suitable atmosphere.
