2005: Discovery of the Sloan Great Wall

by J. Richard Gott and co-authors
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.

Cosmography Update

A 3D map of basins of attractions in the Local Universe, inferred from Cosmicflows-4 and based on a probabilistic approach, gives new insights on our cosmic whereabouts. We have not reached the "End of Greatness" yet!

"Regardless, the beauty of the local universe of galaxies is evident in the image where several huge superclusters of galaxies - clusters of galaxy clusters - can also be seen."
