Is there water outside the earth?

Water is an essential element in our lives. It composes of 70 per cent of our planet and a 65 per cent of the humana life. Water is also found in space being ice one of the most abundant solid materials. But how to arrive there? And how could water molecules in the frozen drakness of interstellar space be formed?

Japanese researches who try to answer these questions created water for the fisrt time in similar conditons to the ones in space.

Water is easily formed here in the sun and abundance of the earth where oxigen and hydrogen are joined. But there isn`t a great quanlity of those elements floating as gas in interstellar clouds. From this research, Japan`s team finishes by saying that water must develop when the atomic hydrogen interacts with frozen oxigen on a solid surface,the same as grains of powder in interstellar clouds.They form this process by creating a layer of oxigen on a substratum of Aluminiun at 10ºkelvin and adding oxigen. By infraring pertrascopie they confirm that, both water and hydrogen peroxide were formed and in suitable quantities as well.In orden to explain the amount of water seen in interstellar clouds we can deduce that the first molecules of water in space must have started in this way, carrying the water to the earth after that.

Space researchers keep surprising us due to the magnitude of their discoveries, as we can see in the great water reserve ever found in space. This discovery was carried out by California`s Technological Institute and Colorado University. The Huge water reserve is found orbitting in cuaser.

The cuaser has the name of APM 08279 5255 which is situated at a distance of 12.000 millions years. Due to this, the image we have of it, is very old when Spain was 1.600 millions years old, which has shown the exitence of water since nearly the proper ougin of the universe with in a radius of and a volume of 140 billions of time which is the sum of water of all the oceans of the earth.
