- Astronomers have mapped the massive Vela Supercluster (Vela-Banzi) for the first time.
- It is located about 800 million light-years away and spans nearly 300 million light-years across.
- The structure lies behind the Zone of Avoidance, making it hard to detect earlier.
- It contains at least 20 galaxy clusters with a mass of about 30 quadrillion suns.
- Observations were made using the Southern African Large Telescope and the MeerKAT radio telescope.
- It is one of the most massive known structures, comparable to the Shapley Supercluster and influences galaxy motion (cosmic flows).
