The Vela Supercluster[1] (Vela SCl, VSCL) is a massive galactic supercluster about 265.5 megaparsecs (870 million light-years)[1] away within the vicinity of the Zone of Avoidance, centered on the constellation Vela. It is one of the largest structures found in the universe, covering about 25 × 20 degrees of the sky. It consists of two walls: a broad main wall and a secondary merging wall. The combined dimensions of the walls are 115 km/s Mpc on the major dimensions and 90 km/s Mpc on the minor ones, which corresponds to about 385 million and 300 million light years, respectively. It is about 1,000 times the mass of the Milky Way galaxy, which corresponds to a mass of 1 × 1015M☉. About 20 initial galaxy clusters have been identified spectroscopically.[1]
