A group of astronomers have unveiled the largest 3D map of the Universe encompassing massive galaxies, distant black holes and all what the limitless sky encompasses.
According to the reports from Washington, astronomers have unveiled the largest ever 3D map of the sky based on Sloan Digital Sky Survey III (SDSS-III) that has revealed the presence of massive galaxies and distant black holes existing in space. The new map that has been made public pinpoints the locations and distances of over a million galaxies. The total volume of the map is equivalent to that of a cube four billion light-years on one side. For more details buy news articles. "We want to map the largest volume of the universe yet, and use that map to understand how the expansion of the universe is accelerating," said Daniel Eisenstein from the Harvard-Smithsonian Centre for Astrophysics, the director of SDSS-III.
This map which has offered the space lovers a new perspective to explore and discover it at a larger and in a lot more detailed way is the centre piece of Data Release 9 (DR9), which publicly releases the data from the first two years of a six-year survey project. According to a Harvard-Smithsonian statement with SDSS-III the release has brought in the open the images of about 200 million galaxies and spectra of 1.35 million galaxies which is a great achievement on the part of the astronomers who had been working over it.

Providing the crucial third dimension and letting the astronomers measure galaxy distances, Spectra takes more time to collect than photograph. “Our goal is to create a catalogue that will be used long after we are done," said Michael Blanton of New York University, who led the team that prepared Data Release 9. This latest release also encompasses new data from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS), which will best work to measure the positions of massive galaxies up to huge distances as far as six billion light-years away and even that of quasars that are giant black holes which are actively feeding on stars and gas which is situated at a distance up to 12 billion light-years from earth. The big bright galaxies which happen to exist in the same places as other galaxies are being targeted by Baryon Oscillation Spectroscopic Survey as they are easy to spot because they exist in close vicinities to each other.

This recent development has undoubtedly broadened the base of the studies and researches related to the vast space that we are surviving in. Mapping the existing big galaxies has provided an effective way to the astronomers for making a map of the rest of the galaxies being present, for retracing the history of the Universe and for estimating the portions of the dark matter. "Dark matter and dark energy are two of the greatest mysteries of our time," said David Schlegel of Lawrence Berkeley National Lab, the principal investigator of BOSS. "We hope that our new map of the universe can help someone solve the mystery."
