Although water accounts for 70% of the planet's surface, scientists still do not agree in where it really comes from. The researchers now stated that they have discovered the origin of water in the earliest moments of the universe existence.
According to scientists from the University of Portsmouth, the country was first formed in the fragments of the Supernova explosion 100-200 million years after the big explosion. These data indicate that the components for life on Earth appeared earlier than before, the Daily Mail wrote.
Using a computer model, researchers show that water can form when the first stars in the universe die and turn into supernova. When the oxygen is formed as a result of these explosions, it is cooled and mixed with hydrogen, water can be formed in the accumulation of the remaining material. These dense dust nuclei are also the most likely source of material that the first planets were formed later, the Daily Mail continued.
In his article, Dr. Daniel Waylen and his co-authors wrote: “In fact, we see that the main component for life has existed in the 100-200 million universe after the big explosion, our model shows that water is probably the important component of the first galaxies.”
Water has H2O chemical formula consists of two components: hydrogen and oxygen. Hydrogen forms with other lighting elements, such as Helium and Lithium, in the first few minutes after the big explosion, when the sea of hot particles is cooled and collected in atoms. However, the oxygen atoms are so large that they cannot form that way. Instead, oxygen and other serious factors should be formed by nuclear reactions that occur in stars.
About 100 million years after the big explosion, about 13.7 billion years ago, the main clouds and Helium clouds gathered together under the influence of gravity. As they became thicker, in the end, the pressure in the core became so big that it offers nuclear synthetic reactions that turn the clouds into stars and bring the first light into the space. Finally, these stars were exhausted with hydrogen fuel reserves and collapsed, causing the appearance of giant super neo. In a short time reaching a temperature of about 1,000,000,000 ° C, these explosions melt raw materials from hydrogen and helium atoms to larger molecules, including oxygen.
In his article, published in the Journal of Natural Astronomy, the researchers simulated what would happen after two Supernova explosions – one of them will come from a star, 13 times higher than the mass of the sun and the second time from a star, the volume is 200 times higher than the mass of the sun. This model shows that in the explosion of the first and second supernova, the solar mass oxygen 0.051 and the mass of solar oxygen 55 sun, formed.
After an explosion, a hydrogen and oxygen clouds were thrown into a large bag, around the rest of the star, where they began to turn into water. At first, due to the low density of the halo, the water level was still quite low, but when the halo began to stick together under the influence of gravity, the water level began to increase sharply.
After 30-90 million years, a smaller supernova produced the equivalent amount of water as one hundredLION or one million solar blocks.
The second explosion, greater, while in only 3 million years of producing 0.001 blocks of water under the sun.
If the country can exist during the storm process of the galaxies, it may be one of the main components of the first galaxies, the Daily Mail wrote.
What makes this discovery is especially interesting that it can explain how water falls on the planet is suitable for life, such as the Earth.
“Nuclei of molecular clouds”, in which the water formed in the largest number, is a possible source of primeval discs, swirling clouds, then forming small planets and stars, like our sun. In some plates, the water level can be almost anywhere else in the universe today.
The researchers wrote: “These disks will be enriched strongly with the main country, their weight will be 10-30 times higher than the clouds that diffuse in the galaxy in the CC Supernova core and only many times less than today's solar system.”
A large amount of water and high probability of the formation of stars in small quantities increases the possibility of liquid water planets that can form after the first supernova explosion.
This means that the main condition for the appearance of life can be completed billions earlier than previous thoughts, concluding Daily Mail.
