Scientists have discovered half of "hidden" mass of the universe.
U.S. astronomers claim that they were able to detect half of "hidden" mass of the universe, the official website of the Hubble Space Telescope. Scientists know that the mass of the visible matter does not correspond to the expected total mass of matter. Regular, consisting of baryons (protons, neutrons and other particles subatomnyh) matter is only 4% mass of the universe, the rest is believed to astronomers, accounted for dark matter, which can be detected only by its gravitational effects on baryons substance.

The space telescope Hubble
The team of astronomers from the University of Colorado at Boulder research light of distant quasars. The scientists took advantage of a spectrograph and ultraviolet spectroscopy Hubble Space Telescope to detect in intergalactic space vysokoionizirovannogo hydrogen and oxygen. According to one of the researchers, Mike Shulla, they managed to find some pautinopodobnuyu structure, which, apparently, is a factual basis for the universe, which astronomers concluded that it was previously empty intergalactic space is, in fact, a "reservoir" normal matter.
