In space, found a giant hole and a huge cluster of galaxies

Scientists have found just two astral phenomenon: the huge space of emptiness and no less than a huge concentration of galaxies, which are extremely large galactic clusters.
 

"One of the detected voids is so great that scientists are at a loss as to how it could have formed", — informs ForUm.

Unusual data were obtained through a network of telescopes SDSS (Sloan Digital Sky Survey), located in the northern hemisphere. The project to scan 41% of the visible celestial sphere has already produced the first results: obtained data on 110,000 galaxies far from Earth at a distance of up to 2 billion light-years. SDSS measured the exact distance, size and position of each with 110,000 galaxies.

In addition to the galaxies themselves, SDSS has made a huge and very detailed map 23% of the visible sky. While the process of studying maps and data analysis is still going, but now scientists say the discovery of the largest known concentrations of the substance, which is a thousand giant galaxies. The resulting congestion has been called the Shapley supercluster, removed from the Earth supercluster 600 million light years away.

SDSS also found an enormous cosmic voids in which there is nothing: no galaxies, no stars, not even a gas or dust. The largest of such empty regions truly huge — about 3.5 billion light-years across. "He is so great, this region is difficult to really appreciate the mentally or visually," — says John Huchra, an astronomer at the Harvard Center for Astrophysics.

Previous "huge void" was about 1 billion light-years in diameter.

According to scientists, the size of the voids is 3.5 billion light years is so large that it does not fit into any of the existing theories on the evolution of the universe today. Presumably, before there were galaxies, but due to a strong external gravitational influence of the other objects from the region of emptiness, they were literally pulled out in the past. Nevertheless, even this proposal does not fully explain the fact of origin of such large voids, writes «CyberSecurity.ru».

Experts believe that if in the future will be able to explain the mechanism of formation of such a large galaxy clusters, as well as to understand how can form huge hollow regions, it will largely be to revise the modern astronomy and astrophysics.

As the correspondent of "City Watch" in Kharkov Observatory, a recent survey of American colleagues aroused Interest from domestic and astrophysicists could fundamentally change the further studies of the galaxy. However, such experiments Ukrainian astrophysics have no money.

Recall that in early March, Australian scientist Robert MakNaud discovered in the constellation Feed unidentified flying object. Soon he was identified as an asteroid. Celestial body was given the 19th star size, which corresponds to our 35 meters.
