What it is

A wall of galaxies more than a billion light-years long, found by the Sloan Digital Sky Survey in 2003. It is placed here on its richest supercluster.

Placed by its redshift, at the distance the expansion has carried it to by now; the dots around it are galaxies of the 2MASS and SDSS surveys, placed the same way.
