The Abell 901/902 supercluster is just over two billion light-years from Earth.

Superclusters are large collections of smaller galaxy groups and galaxy clusters. They are one of the largest known structures in the cosmos.

Superclusters show that the galaxies in the universe are not evenly distributed. Most, perhaps all, are in groups and clusters. Groups have some dozens of galaxies, and clusters up to several thousand galaxies. Those groups and clusters plus more isolated galaxies form even larger collections called superclusters.

Superclusters themselves form even larger structures, called "filaments", "complexes", "walls" or "sheets", like the Great Wall. These may span between several hundred million light-years to 10 billion light-years, and cover more than 5% of the observable universe. Superclusters suggest something about the initial condition of the universe when these superclusters were formed. The directions of the rotational axes of galaxies within superclusters may also tell us about the formation of galaxies early in the history of the Universe.

Inside superclusters are large voids of space in which few galaxies exist. Superclusters are often subdivided into groups of clusters called "galaxy clouds".
