A team of scientists led by the National Radio Astronomy Observatory (NRAO – USA) has identified signs of the “source of life” in the protoplanetary disk of a young star named V883 Orions.
According to Sci-News, the groundbreaking data was recorded by ALMA is the most powerful radio astronomy observing system in the worlda US-Chilean cooperative project located in the Atacama “death” desert in Chile.
“The Eyes of God” from ALMA provided an extremely valuable sign proving the hypothesis that water on Earth – “cradle” of life – existed before the official birth of the Sun. Water is one of the main factors in determining whether a planet is habitable.
Molecules with values such as “nursery“This life has also been analyzed through the appearance of the heavy isotope of hydrogen, deuterium.

Because water is simple and Heavy water contains deuterium Instead of hydrogen isotopes, conventional hydrogen isotopes form under different conditions, so their ratio can be used to track time and determine where water is forming.
For example, this ratio in some comets in the Solar System has been determined to be similar to that on Earth, suggesting that the comets may be of the same type as those that brought water to the early Earth.
Something unexpected happened in the new study: The ratio of pure water molecules to deuterium-rich water in the world around V883 Orions is similar to that of our solar system and Earth..
Proving that Earth’s water is older than the Sun and of the same type as other distant worlds also indirectly strengthens the life hypothesis and that everything essential for life on Earth today has been nourished in interstellar space. In other words, we are people of extraterrestrial origin who were seeded on Earth by asteroids and comets, as well as by the elements necessary for our survival.
In the world around the V883 Orions, there may be these “Another land” are born in the same way.
Co-author astronomer Margot Leemker of Leiden University – Netherlands explains: “Most of the water in the interstellar medium forms as ice on the surface of small dust grains in molecular clouds. When these clouds collapse under their own gravity and form young stars, the water is found in the plates that surround them.”
“Eventually, the disks grow and the icy dust particles solidify to form a new ‘solar system’ with planets, comets…” – he added how the world of the constellation Orion and other worlds, including ours, were born with water.
The research has just been published in a scientific journal Nature.
