Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The existence of superclusters indicates that the galaxies in our Universe are not uniformly distributed; most of them are drawn together in groups and clusters, with groups containing up to 50 galaxies and clusters up to several thousand. Those groups and clusters and additional isolated galaxies in turn form even larger structures called superclusters. Once thought to be the largest structures in nature, superclusters are now understood to be subordinate to enormous walls or sheets, usually called filaments", sometimes called "super cluster complexes", "walls" or "sheets", that can span a billion light-years in length, more than 5% of the observable universe."
