A new map developed by an international team of astronomers should help you find your way around the Universe – at least to a distance of 600 million light years. This new 3-dimensional map plots out the locations of all the major superclusters of galaxies and the voids that surround them. It includes „The Great Attractor“ and a supercluster called „Shapley“ that lies about 400 million light years away and spans 20 million light years. The map was developed using data from the 2MASS Redshift Survey, which calculated the redshifts (and therefore the distances) of 25.000 galaxies across the entire sky, and the Two Micron All Sky Survey, which provided the colours and two-dimensional positions of the galaxies.
