Prior Identified Superclusters
Contemporary catalogs of superclusters range from relatively smaller systems such as the Hercules supercluster (Abell 1961) to the much more massive Shapley Concentration containing several major clusters and numerous groups (Raychaudhury 1989; Bardelli et al. 2000; Proust 2006).
More recently, a new supercluster called Laniakea, spanning ∼ 160 Mpc across, is identified (Tully et al. 2014) which is home to our Milky Way galaxy.
Laniakea - The Supercluster that Contains Earth and Its Sun____________________
Another large, wall-like structure spanning ∼ 250 Mpc was discovered in the SDSS-BOSS survey
(the BOSS Great Wall) at redshift 0.47 (Lietzen et al. 2016).
