'That word' (below-hyperlinked to a post about 'the Composition of things') is built on an even-deeper source ... something crucial that firms the foundation upon which our lexicon stands ...
The word “Supercluster (Cluster)” is built on words that mean “a number of |Things, Persons or |Animals-Growing Naturally Together or -|Gathered in a |Close Body” (same Foundation as |Clot).

Galaxy supercluster Data Notes Laniakea Supercluster The Laniakea Supercluster is the supercluster that contains the Virgo Cluster, Local Group, and by extension on the latter, our galaxy; the Milky Way.[2] Virgo Supercluster
- z= 0.000
- Length = 33 Mpc (110 million light-years)
It contains the Local Group with our galaxy, the Milky Way. It also contains the Virgo Cluster near its center, and is sometimes called the Local Supercluster. It is thought to contain over 47,000 galaxies.
In 2014, the newly announced Laniakea Supercluster subsumed the Virgo Supercluster, which became a component of the new supercluster.[8]Hydra-Centaurus Supercluster It is composed of two lobes, sometimes also referred to as superclusters, or sometimes the entire supercluster is referred to by these other two names
- Hydra Supercluster
- Centaurus Supercluster
In 2014, the newly announced Laniakea Supercluster subsumed the Hydra-Centaurus Supercluster, which became a component of the new supercluster.[8]Pavo-Indus Supercluster Southern Supercluster Saraswati Supercluster Distance = 4000 Million light years (1.2 Gpc)
Length = 652 Million light-yearsThe Saraswati Supercluster consists of 43 massive galaxy clusters such as Abell 2361 and has a mass of about 2 x 1016 M☉ and is seen in the Pisces constellation Distant superclusters
Galaxy supercluster Data Notes Perseus-Pisces Supercluster Coma Supercluster Forms most of the CfA Homunculus, the center of the CfA2 Great Wall galaxy filament Sculptor Superclusters SCl 9 Hercules Superclusters SCl 160 Leo Supercluster SCl 93 Ophiuchus Supercluster
- 17h 10m−22°
- cz=8500–9000 km/s (centre)
- 18 Mpc x 26 Mpc
Forming the far wall of the Ophiuchus Void, it may be connected in a filament, with the Pavo-Indus-Telescopium Supercluster and the Hercules Supercluster. This supercluster is centered on the cD cluster Ophiuchus Cluster, and has at least two more galaxy clusters, four more galaxy groups, several field galaxies, as members.[9] Shapley Supercluster
- z=0.046.(650 Mly away)
The second supercluster found, after the Local Supercluster. Incredibly distant superclusters

Galaxy supercluster Data Notes Hyperion proto-supercluster z=2.45 This supercluster at the time of its discovery in 2018 was the earliest and largest proto-supercluster found to date.[11][12] Lynx Supercluster z=1.27 Discovered in 1999[13] (as ClG J0848+4453, a name now used to describe the western cluster, with ClG J0849+4452 being the eastern one),[14] it contains at least two clusters RXJ 0848.9+4452 (z=1.26) and RXJ 0848.6+4453 (z=1.27) . At the time of discovery, it became the most distant known supercluster.[15] Additionally, seven smaller groups of galaxies are associated with the supercluster.[16] SCL @ 1338+27 at z=1.1 A rich supercluster with several galaxy clusters was discovered around an unusual concentration of 23 QSOs at z=1.1 in 2001. The size of the complex of clusters may indicate a wall of galaxies exists there, instead of a single supercluster. The size discovered approaches the size of the CfA2 Great Wallfilament. At the time of the discovery, it was the largest and most distant supercluster beyond z=0.5 [17][18] SCL @ 1604+43 at z=0.9 z=0.91 This supercluster at the time of its discovery was the largest supercluster found so deep into space, in 2000. It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it. The then known clusters were Cl 1604+4304 (z=0.897) and Cl 1604+4321(z=0.924), which then known to have 21 and 42 known galaxies respectively. The then newly discovered cluster was located at 16h 04m 25.7s, +43° 14′ 44.7″[19] SCL @ 0018+16 at z=0.54 in SA26 z=0.54 This supercluster lies around radio galaxy 54W084C (z=0.544) and is composed of at least three large clusters, CL 0016+16 (z=0.5455), RX J0018.3+1618 (z=0.5506), RX J0018.8+1602 .[20] MS 0302+17 This supercluster has at least three member clusters, the eastern cluster CL 0303+1706, southern cluster MS 0302+1659 and northern cluster MS 0302+1717.[21]

I appreciate your comment, and I'll probably approve it & publish it soon (give me about a week before you try to post it again when it doesn't publish immediately ... thanks)
