A team led by Conel Alexander at the Carnegie Institution in Washington, DC reported, that the main suppliers of water on Earth were an asteroids, but were not a comets, as previously thought. This conclusion was made on the basis of a study of the isotopic composition of water in the fragments of carbonaceous chondrites, which formed as a result asteroids falling to Earth in the distant past. According to Konel Alexander, the isotopic composition of water, which was found inn these carbonaceous chondrites are very similar to the isotopic composition of water in the modern oceans, and very different from the isotopic composition of the substance of comets. Therefore, according to the scientist, the main source of water were asteroids located between Mars and Jupiter, because of the crust of Mars should contain the same amount of water, than the earth's crust.
