What are superclusters?
Q: What are superclusters?
A: Superclusters are large collections of smaller galaxy groups and galaxy clusters, forming some of the largest known structures in the cosmos.
Q: Are galaxies evenly distributed in the universe?
A: No, galaxies in the universe are not evenly distributed.
Q: What are groups and clusters in the context of superclusters?
A: Groups have some dozens of galaxies, and clusters up to several thousand galaxies.
Q: What are the larger collections formed by groups, clusters, and isolated galaxies?
A: They form even larger collections called superclusters.
Q: What are the larger structures that superclusters themselves form?
A: They form even larger structures called "filaments", "complexes", "walls" or "sheets", like the Great Wall.
Q: What percentage of the observable universe do these larger structures cover?
A: They cover more than 5% of the observable universe.
Q: Are there many galaxies inside superclusters?
A: Yes, there are many galaxies inside superclusters, but there are also large voids of space in which few galaxies exist. Superclusters are often subdivided into groups of clusters called "galaxy clouds".
