Many researches have been done on the subject of where did water on earth come from. The funny thing in this is that sometimes it was told that water on Earth came from asteroids and meteorites, and sometimes it was also said that water formed on Earth itself and remained here from the beginning. Most of these researches have been done on the fragments of meteorites and asteroids that have fallen on the Earth. The new study analyzed an ancient asteroid sample obtained from Japan's 2010 Hayabusa mission. This study has shown that the water on Earth came from the dust particles of space, from which the planets were formed.
Role of solar wind
The study, conducted by researchers from the UK, Australia and the US, found that water was formed in dust particles when charged particles called the solar wind coming from the Sun changed the chemical composition of the dust particles in space, causing them to water molecules can be produced.
So much water in the oceans
Scientists call this process space weathering. In this study published in the journal Nature Astronomy, scientists have told that it is a very challenging task to create a water structure in Earth's oceans by mixing materials from sources like asteroids. But solar winds can answer this question.
These reasons have been given so far
Planetary scientists have been wanting to know for a long time how did so much water get into Earth's oceans. Some theories have suggested that this may have been caused by the rain of watery asteroids that hit Earth 4.6 billion years ago. Researchers believe that some water on Earth came from a 'C' type asteroid.
This investigation will be very useful
Researchers also believed that with this, the water on Earth must have come from another mild isotopic source that was elsewhere in the solar system. The new investigation will also reveal many mysteries surrounding the arrival of water on Earth and the amount of large amounts that surround the surface. Scientists are also hoping that the results of this study will be helpful in future space missions to find water on airless planets.
Study of space rock samples
The international team, led by scientists from the University of Glasgow, studied samples of different types of space rocks using atom probe tomography. These rocks are called S-type asteroids, which orbit the Sun by staying closer to them than C-type asteroids.
Water molecules in samples
These samples were from the Itokawa asteroid and analyzed them. When scientists studied the molecular structure of one atom at a time, it was found that they have the presence of water molecules. The lead author of this study, Dr. Luke Daley, explained how these water molecules reached or formed in them.
Scientists are also surprised by the discovery of Chinese rover, a 'mysterious' hut seen on the Moon
This incident has been told in the diary, published on the Chinese science channel Our Space, working with China's space agency National Space Administration (CNSA). The diary said that saw a cube-shaped object on the horizon to the north of the Moon.
