Study materials obtained space probe Rosetta, studying the comet Churyumov-Gerasimenko, showed that the water on Earth came not from the family comets Neptune, as previously thought, but on the other celestial bodies - likely asteroids.
Kathrin Altwegg, a member of the University of Bern in Switzerland, conducted a study of data obtained cpektrometrom space probe Rosetta, and found on the surface of the comet Churyumov-Gerasimenko, the frozen water. However, it is not dominant on the planet H20, and the so-called heavy water - 2H2O, according to National Geographic.

Heavy water instead of two atoms of ordinary light isotope of hydrogen - Against - contains two atoms of heavy isotope of hydrogen - deuterium. Externally, it is no different from the usual.


Light water on the comet Churyumov-Gerasimenko is also present, but the ratio of heavy water to the volume of light is three times that of the Earth. If, as previously thought, brought water to the Earth comet from the so-called Kuiper Belt beyond Neptune's orbit, which belongs to the comet Churyumov-Gerasimenko, the percentage of heavy and light water on the planet would have been different.

As other possible sources of water for Earth scientists call asteroids and comets Oort Cloud - a hypothetical spherical region of the solar system, serving as a source of long-period comets.

"We knew that Rosetta will bring us surprises," - said one of the program managers Matt Taylor from the European Centre for the Study of the cosmos. - We got more knowledge about the solar system, and it is an outstanding observation inflame the debate on how the Earth to get water. "

In November Rosetta probe made the first in the history of space exploration landing on the comet 67P / Churyumov-Gerasimenko and even published in the microblogging on Twitter photos from the surface of a celestial body. The unit overcame about 6.4 billion. Km to reach the comet and to find new clues that could help shed light on the appearance of our solar system and life on planet Earth.
