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.
This fantastic skyscape lies near the edge of NGC 2174 - a star forming region about 6,400 light-years away in the nebula-rich constellation of Orion. It follows mountainous clouds of gas and dust carved by winds and radiation from the region's newborn stars, now found scattered in open star clusters embedded around the center of NGC 2174, off the top of the frame.
Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes.
