    Galaxy redshift surveys, such as the SDSS imaged here, map an incredible dynamic range: from star forming regions within galaxies out to the large-scale distribution of millions of galaxies -- the "cosmic web" of our local Universe.  SDSS-III DR12, released in early 2015, represents the completion of million of spectra obtained from several million galaxies within this image.
