Astronomers have been mapping vast cosmic structures for decades, from galaxy clusters to immense superclusters. But researchers have identified, they say is officially the largest known object in universe—a massive cosmic structure stretches 1.4 billion light-years across & contains nearly 70 galactic superclusters recently. It
discovered structure is called Quipu. Found by a team of astronomers led by Hans Böhringer @Max Planck Institute for Physics in Munich, Germany. Name comes from an ancient Incan counting system made of knotted ropes,
visually resembles vast interconnected web of galaxies that make up this structure. Quipu surpasses previous record-holding largest cosmic objects, including the Sloan Great Wall & the Laniakea Supercluster, both of which were once considered the largest formations in the known universe.

The researchers found Quipu while analyzing data from the ROSAT X-ray satellite, a German mission designed to detect high-energy cosmic structures like galaxy clusters big enough to warp space-time. To help make work more efficient, they turned to an algorithm that could determine which galaxy clusters were linked. The data helped them define maximum distance threshold beyond clusters could no longer be considered part of the same system. Researchers say Quipu was so obvious in the data that it immediately caught their attention. Finding largest known object in universe isn’t just exciting achievement, though. It also raises some great questions about how our universe is structured to cosmological principle, the universe should appear roughly uniform at vast scales. However, the existence of these gigantic, clumped-together structures seems to contradict this idea.
