When autumn evenings get darker in the sky is visible wide shimmering band. This milky Way - a giant arch spanning the entire sky. "The heavenly river" is called the milky Way in Chinese tales. The ancient Greeks and the Romans called it "Heavenly road". The telescope gave the opportunity to clarify the nature of the milky Way. It is the radiance of the innumerable stars are so distant from us that they individually impossible to distinguish with the naked eye.

In telescopes in any part of the milky Way seen countless number of stars. The slower the shutter speed, with which you are photographing, the greater is very far from us stars detected in all regions of the milky Way.

In the Northern hemisphere of the milky Way passes through the constellations of the eagle, Arrows, Foxes, Swans, Cepheus, Cassiopeia, Perseus, Auriga, Taurus and Gemini. Leaving in the southern hemisphere, it captures the constellation of the Unicorn, the Stern, Sail, the southern cross, a Compass, South Triangle, Scorpio, Sagittarius. Continuous ring spreading the milky Way in the sky, having different widths, different brightness and complex shapes along its entire length. It is especially bright in the constellation of Sagittarius, which in our latitudes, high above the horizon does not rise. Therefore in this area of the milky Way is not so noticeable as, say, in the constellation of Cygnus, which fall in the evenings rises very high.

In 2000 year, astronomers have discovered hydrogen, which, they claimed, was formed during the Big Bang. This discovery confirms current theories on the structure of the Universe.

A group of astronomers led by Donald Lubovitch from Hofstra University reported in the latest issue of the journal Nature about the discovery of deuterium, an isotope of hydrogen in the gas cloud near the center of the galaxy.

Astronomers have found the deuterium molecules of hydrogen cyanide in addition to carbon and nitrogen in the cloud of Sagittarius A, the remote on 30 light years from the center of the milky Way and 25,000 light years from Earth.

Deuterium was discovered by 12-metre telescope (millimeter-wave telescope)

The discovery of deuterium in the center of the milky Way was not unexpected: the results of past observations allow to assume that there exists a heavy isotope of hydrogen. Using new observations, astronomers have determined that for every million hydrogen atoms have one atom of deuterium is quite a small number, but it is a million times more than expected.

Astronomers believe that this hydrogen is a primordial hydrogen, which was formed within the first few minutes after the Big Bang. They have excluded other sources, such as the formation of stars or collisions with other atoms with cosmic rays.

The lubovitch with colleagues believe that the deuterium comes from clouds of gas that surround our galaxy, or directly from intergalactic space.

It is not known whether gas clouds, which can provide the galaxy deuterium, with a giant gas clouds, found in the last year above the plane of the milky Way. Found that those clouds poor heavy elements, they consist almost entirely of hydrogen and helium, and can help to maintain the current rate of star formation in the galaxy.

This discovery confirms the current model of the structure of the Universe. Astronomers believe that approximately four percent of the mass of the Universe falls on ordinary matter. This is consistent with other recent studies that suggest the number of ordinary matter is five percent of the mass of the Universe.
