Quipu (supercluster)
Quipu is a large-scale superstructure of galaxies of the Universe, a wall of galaxies or galaxy hypercluster composed of knots of galaxy clusters. As of 2025, it is the largest known structure in the Universe, some 1.3×109 light-years (7.6×1021 mi; 1.2×1022 km) long; and the most known massive structure, containing 2×1017 solar masses (4.0×1047 kg; 8.8×1047 lb; 4.0×1044 t).[1][2]
The structure was discovered by Hans Böhringer and colleagues using data from the ROSAT X-ray satellite, and described in a 2025 paper on arXiv. It was named "quipu" as it is reminiscent of the Andean knotted textile called quipu that Böhringer had seen in a museum near Santiago, Chile, while he was working at the European Southern Observatory.[3][4]
