About the Sloan Great Wall

The light we see from it set out 1 billion years ago, when the universe was 12.8 billion years old (redshift 0.073).

The map lists it as a large-scale structure and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

A wall of galaxies about 1.37 billion light-years long (Gott et al. 2005).

From Wikipedia

The Sloan Great Wall (SGW) is a cosmic structure formed by a giant wall of galaxies. Its discovery was announced from Princeton University on October 20, 2003, by J. Richard Gott III, Mario Jurić, and their colleagues, based on data from the Sloan Digital Sky Survey.
