Astronomers believe the biggest 3D map of the Universe

Incredibly we consider the recent creation of several researchers from Brookhaven National Laboratory . Astronomers have made ​​the construction of the largest 3D map (and old) ever created. A map can cover a swath that covers between 10 billion and 12 billion light years away that could finally give the answers to many questions of science, including the nature of dark energy or the location of galaxies beyond the 7 billion light years (the previous record of a map of the same characteristics).

For the realization of the map is based on the powerful light emitted in the cosmic distance markers 14,000, thus the depth map in time ever created. Hydrogen clouds could help answer some major questions about the universe.

The instrument used to create the map, Barion Oscillation Spectroscopic Survey (also called BOSS) is a multipurpose telescope capable of analyzing the light from quasars (astronomical source of electromagnetic energy, including visible light and radio frequencies) so individual. Anze Slosar , head researcher of the project, explained:

We seek a blow that does not provide data that can tell us how fast the universe is expanding, at what speed. Until now we did not have enough data to it, but hope to find soon. Quasars are extremely bright galaxies that are far away. In the center of each black hole is eating the matter. This matter is heated to very high temperatures and radiate and shine. This allows us to see from an extremely distant

What you get with this 3D map is to move to trace the development of clusters of galaxies between 10 billion and 12 billion years, analyzing 14,000 of the approximately 160,000 known quasars, estimating that by 2014 will reach to 60,000 . The chart below shows that ended with the essence of the map. At the same we can see there are new data on emissions of hydrogen gas between these 10 billion and 12 billion light years away.
