- The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which itself contains the Milky Way and Andromeda galaxies, as well as others. 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.
- Star Tales - Draco (ianridpath.com)
Coiled around the sky’s north pole is the celestial dragon, Draco, known to the Greeks as Δράκων (i.e. Drakon). Legend has it that this is the dragon slain by Heracles during one of his labours, and in the sky the dragon is depicted with one foot of Heracles (in the form of the neighbouring constellation Hercules) planted firmly upon its head. This dragon, named Ladon, guarded the precious tree on which grew the golden apples.
