Superclusters are large groupings of smaller galaxy groups and clusters, and are among the largest structures of the cosmos.
Superclusters
The clustering phenomenon does not stop with galaxies. Galaxy clusters attract each other to produce superclusters of tens to hundreds of clusters.
Superclusters
After astronomers started grouping galaxies into clusters they noticed that on larger scales the clusters tended to be grouped together in clusters or what we call Superclusters (what a clever name - sounds almost like a superhero).

Superclusters contain tens of thousands of galaxies, which are found in clusters, groups and sometimes individually. At the supercluster scale, galaxies are arranged into sheets and filaments surrounding vast empty voids.
These large-mass perturbations are identified today as the largest known superclusters of galaxies. Subsequent cooling and fragmentation within the overall density perturbation then produces smaller-scale clusters of galaxies (of mass 1014-1015 M).
There have been indications that clusters within superclusters are preferentially aligned, which if true would suggest dynamical processes that can leave a very long-lasting imprint. Following A.
We can infer its presence in galaxies and galaxy clusters, but we are largely ignorant of its extent in superclusters, voids, or other larger structures.
Overall, the distribution of clusters and superclusters in the universe is not uniform. Instead, superclusters of tens of thousands of galaxies are arranged in long, stringy, lacelike filaments, arranged around large voids.
LARGE-SCALE STRUCTURE - Structures composed of galaxy superclusters, galactic sheets, filaments and voids that span significant fractions of the observable Universe.
As CMB photons travel through superclusters of galaxies they first become blueshifted by the cluster's gravity, and upon leaving the cluster become redshifted again.
Groups and Clusters cluster together to form even larger clusters known as Superclusters. The Local Group belongs to the Local Supercluster, whose center is at the Virgo Cluster. Superclusters, on average, span 100 Million Light-years of space.
These superclusters then form surfaces like the surfaces of bubbles, with virtual voids in between (Margaret J. Geller, John P. Huchra and Valerie De Lapparen, 1986).
Although we have talked about hierarchical clustering almost exclusively in the context of the formation of galaxies, it is also an important mechanism on much larger scales - those of galaxy clusters and superclusters.
Galaxies are organised into groups and superclusters of anywhere from a few to millions of galaxies. Our galaxy's group, the oh-so-originally named Local Group, contains many galaxies, of which ours is the second largest.
We don't know for sure that we live in a matter Universe, only that individual superclusters of galaxies are each made of either matter or antimatter.
Large-scale structures, such as galaxies, clusters, and superclusters, had their frameworks laid in the initial giant clouds of gas.
Groups, clusters and some isolated galaxies form even larger structures, the superclusters. At the very largest scales of the visible universe, matter is gathered into filaments and walls surrounding vast voids. This structure resembles a foam.
In our epoch, large concentrations of galaxies (clusters and superclusters) are still assembling. This "bottom-up" picture is referred to as hierarchical structure formation (similar to the SZ picture of galaxy formation, on a larger scale).
void Large, relatively empty region of the universe around which superclusters of galaxies are organized.

In a larger scale, clusters group together to form superclusters. It contains about 100 clusters in 100 Mpc (mega parsec, a million parsecs).
large-scale structure: The distribution of galaxy clusters and superclusters in walls and filaments surrounding voids mostly empty of galaxies.
" Gravitation also acts to group billions of stars into galaxies and to group galaxies into clusters and superclusters.
A vast collection of galaxy clusters that may contain tens of thousands of galaxies spanning over a hundred million light-years of space. Galaxy superclusters are the largest structures in the universe.

These tend to be shaped as flattened disks, sheets, or filaments. These superclusters then form surfaces like the surfaces of bubbles, with virtual voids in between. These may be the largest structures in the universe.
A cluster of clusters of galaxies. Superclusters are typically about one hundred million (108) light-years in diameter and contain tens of thousands of galaxies.

For example, stars in the Milky Way can group together into open clusters or globular clusters. Galaxies also group together into cluster of galaxies, and the clusters of galaxies group together into superclusters of galaxies.

The Catalog proved of seminal importance to extragalactic astronomy, leading to a better understanding of the nature and properties of clusters of galaxies, and the identification of superclusters and large-scale structure.
