The Sloan Digital Sky Survey III (SDSS-III), after making the largest and deepest of the night sky photography captured so far, now wants to expand that image and presented a three-dimensional map of massive galaxies and black holes away. This map has a press release in the Canary Islands Astrophysics Institute, which works with the project, will help astronomers to explain two of the great mysteries of modern science: dark matter and dark energy.
The collaboration has also released an instructional video which shows a simulated journey through the universe of galaxies in the SDSS project. The animation shows over 400 000 galaxies in their observed positions and real images of the same. Each of the points of light seen is a galaxy containing billions of stars and planets.
The 3D map, the key to the ninth publication of data that made this collaboration, is available on the pages http://www.sdss3.org/dr9 and http://skyserver.sdss3.org. Among the content that can find no images of 200 million galaxies and over a million spectra. Of these, 540 thousand are galaxies, most had not been studied previously and we see them as they were when the universe was half its current age, which is about 13.7 million years.
