DavinaAlcindor1 1)The atom of hydrogen is the simplest atom which is: he(it) consists only of a proton associated with an electron. It is also the most present atom in the universe, because he(it) represents approximately 92 % of his(its) atoms and 70 % of his(its) mass.

DavinaAlcindor1 2)The oxygen is(is a matter) of a much more complex process: it is an atom established(constituted) by eight protons and by eight neutrons, he(it) is sixteen times as heavy as the hydrogen. It is up to the groups of the heavy elements (by opposition to the light elements) and did not form just after the birth of the Universe, but just after the birth of the first stars.

DavinaAlcindor1 3)There is so much water on earth(ground) because The hydrogen, him, is in abundance in the universe. He(it) represents with the helium more than 99 % of the atoms of the universe. He(it) was trained(formed) by captation of an electron (loaded(charged) negatively) by a proton (loaded(charged) postivement).

For the oxygen it is more complicated... It is necessary to know that all the atoms of the universe were trained(formed) in stars from the hydrogen. Hey yes!

DavinaAlcindor1 4) La différence d'une magnitude la différence de marche

DavinaAlcindor1 5) Ils sont situés au Chili le E-ELT est précisément situé à Cerro Armazones dans le désert d'atacama et le VLT est à Cerro Paranal dans le désert d'Atacama aussi .

DavinaAlcindor1 6)They hope to find advances(overhangs) significant in of numerous domain, it is has to say answers has questions or answers has hypotheses.
The astronomers so so hope to study the environment of stars in training(formation) and to open new windows on the exit(release) of the dark Ages.
