Virgo: August 21– September 20 earth Virgo is the Goddess of Innocence and Purity, Astraea. According to the creation myth, Zeus sent Pandora down to Earth as a punishment to man. Because of her curiosity, she opened the box the gods had warned her not to, and let the plagues of hate, envy, sickness, etc. out into the world. Of course, Hope did not escape, but the Earth was just unbearable. One by one, the gods returned to the heavens to live. Astraea was the last to leave. She became the constellation Virgo, and according to legend, when the Golden Age comes again, Astraea will return to the Earth. Constellation: The Virgo Supercluster or the Local Supercluster is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which in turn contains the Milky Way and Andromeda galaxies. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs [110 million light-years]. The Virgo SC is one of about 10 million superclusters in the observable universe and is in the Pisces–Cetus Supercluster Complex, a galaxy filament. A 2014 study indicates that the Virgo Supercluster is only a lobe of an even greater supercluster, Laniakea, a larger, competing referent of Local Supercluster centered on the Great Attractor.
