43,000 Galaxies on a Map / the most complete map of our local universe to date. It took more that ten years to create, has 43,000 galaxies and extends out 380 million light years from the earth. The 3D coordinates of each galaxy was recorded so the raw data could potentially be used to build a realistic 3D model of the universe.
