SCIENTISTS: WATER IN THE UNIVERSE ORIGINATED BEFORE THE FORMATION OF THE SOLAR SYSTEM
According to a new study by researchers from the University of Michigan, published in the journal Science, about 30-50% of the water that is in the world, on the ice of comets disk around Saturn and meteorites appeared before the birth of the Sun .
Scientists claim that the water originated in the molecular cloud – a nebula in which the sun appeared millions of years ago. To prove this, astronomers had a computer simulation of chemical processes of formation of the solar system. The model contains two types of water: plain water and a “heavy” water, which can be found in comets, meteorites, the Earth’s oceans and other cosmic bodies.
Ordinary water containing hydrogen, whereas “heavy” contained isotope deuterium, which is different from the number of neutrons generated and hydrogen in cold conditions. Scientists have carried out re-modeling without the inclusion of “hard” water, so the solar system was to form water from the ground. They found that the system was unable to reach an amount of deuterium, which was found in the water samples of the solar system.
The conclusions drawn from these studies , are quite interesting. If water is formed locally in each star system, its amount and the amount of chemical elements required for the formation of life may vary from system to system.
However, if you believe the research, each planetary system received water from the nebula, so the amount of water and chemical elements in all systems should be about the same. And this, in turn, pushes us to think that somewhere in space can exist planetary system similar to our solar system.Viewing:-132
