Is the mystery of the origin of water on Earth finally solved?

Not just our earth Rock planet Of The Solar System. But it still has one characteristic that others do not have: it Covered in water More than 70%! Researchers have long questioned its appearance. Today a Group led by the University of Glasgow (Scotland) argues that Solar wind, Especially made of ions Hydrogen, On the surface of small dusts, can form a water that has stained the earth Asteroids This would have crossed the path of our planet at the beginning of the history of our solar system.

Remember that this includes one of the hypotheses that explains the existence of water on earth Conflicts with asteroids Type C – carbonaceous asteroids, 75% asteroids, etc. – in the final stages of our planet’s formation. But the isotopic trace of these substances does not match exactly. Another source appears to be needed.

Water for space missions

So researchers say S-type asteroids – asteroids are mostly made of silicates. And they conducted a thorough analysis of a few grams of dustIdokawa Asteroid Brought back to Earth in 2010. Thanks to a nuclear tomographic study, this makes observation possible Resolution Spatial distribution Atoms In one model, scientists actually approached the top 50 Nanometers From the surface of these dust grains. They are equivalent to 20 liters of water per cubic meter. Water is isotopically lighter than it could have come to Earth From Type C asteroids. The path is good.

Researchers also hope that their work will be effective Future space missions. This is because they show that the same meteorological process that created water in Idokawa may have occurred on planets that are not in the atmosphere. And so on Astronauts Cold water can be collected directly from the dust on the surface நிலா, For example.
