A few are found alone but almost all are grouped in formations termed galactic clusters. These formations should not be confused with stellar clusters globular clusters of stars that exist within a galaxy. The size of galactic clusters varies enormously with some clusters containing only a dozen or so members and others containing as many as 10 000. Moreover galactic clusters themselves are part of larger clusters of clusters termed superclusters. It is surmised that even clusters of superclusters are possible. Our galaxy the Milky Way is part of a galactic cluster called the Local Group which has twenty members and is typical in terms of the types of galaxies it contains. There are three large spiral galaxies Andromeda the largest galaxy in the group the Milky Way the second-largest galaxy and the Trianglum Spiral the third largest. There are also four medium-sized spiral galaxies including the Large Cloud of Magellan and the Small Cloud of Magellan. There are four regular elliptical galaxies the remainders are dwarf ellipticals. Other than our own galaxy only Andromeda and the Clouds of Magellan can be seen with the naked eye and the Clouds are visible only from the Southern Hemisphere. In the vicinity of the Local Group are several clusters each containing around twelve members. The nearest cluster rich in members is the Virgo Cluster which contains thousands of galaxies of all types. Like most large clusters it emits X-rays. The Local Group the small neighboring clusters and the Virgo Cluster form part of a much larger cluster of clusters - the Local Supercluster. The existence of galactic clusters presented a riddle
