"The Vela Supercluster is roughly 300 million light-years across, making it around 3,000 times wider than the Milky Way itself, far more massive than previously thought."
"The researchers studied the behavior of galaxies at the Vela Supercluster's edge to determine its size, using observations by two South Africa-based facilities."
"The MeerKAT radio telescope can detect the presence of hydrogen gas at radio wavelengths which pass through the Milky Way's dense cloud of dust."
"The millions/billions of stars forming the disk are so dense and so close to the galactic plane that we cannot easily see through it."
The Vela Supercluster, discovered in 2016, consists of at least 20 galaxy clusters and is located 800 million light-years from Earth in the Zone of Avoidance. Researchers have now mapped this supercluster, finding it to be approximately 300 million light-years across, significantly larger than earlier estimates. The study utilized observations from the Southern African Large Telescope and the MeerKAT radio telescope to analyze galaxies at the supercluster's edge, enhancing understanding of cosmic structures and cosmology.
