The 2MASS Redshift Survey (details here) took 10 years to complete, and it has now yielded the finest 3D map of the universe ever made, cataloguing more than 43,000 galaxies within 380 million light-years from Earth. The new map was presented last week at the 218th meeting of the American Astronomical Society. You can view the map in a much bigger format here and, as one user suggests, you may want to “right click and save as desktop background.”
