2005: Discovery of the Sloan Great Wall

by J. Richard Gott and co-authors
https://doi.org/10.1086/428890

At the time of its discovery, this 1.37 billion light-years long filament is the largest observed structure in the Universe.

The distribution of galaxies obtained with the Sloan Digital Sky Survey and displayed as two fan-shaped plots with Right Ascension versus redshift distances as coordinates. Galaxies' positions are shown as black points on a white background, featuring filamentary structures typical of the Cosmic Web, which describes the large-scale structure of the Universe. The two fan-shaped plots lie on top of each other, with their boundaries elegantly matching each other's. On the lower plot, running from 0 to 14000 km/s in redshift, and from 8 to 17 hours in Right Ascension, is shown the CfA2 Great Wall, with its iconic stickman-shaped distribution of galaxies. On the higher plot, running from 14000 to 28000 km/s in redshift distances, and from about 9 to 14 hours in Right Ascension, is featured the Sloan Great Wall. A caption completes this figure.
