359-cosmic-structure-dixon Large Scale Structure of Universe - This theoretical cosmological diagram illustrates the structural hierarchy and scale of matter distribution in the universe, arranged in a counter-clockwise loop of spherical vignettes connected by expanding blue field cones. The sequence scales upward from an individual, finely detailed blue spiral galaxy at the top-left, moving through a localized group of galaxies, a massive galaxy cluster populated by hundreds of points of light, and a broader supercluster network. The culmination on the right shows the large-scale cosmic web structure of filaments and voids, which eventually smooths out at the maximum scale into a homogeneous, uniform lavender sphere, demonstrating the cosmological principle where the universe becomes uniform on its largest scales. digital painting by Don Dixon for Scientific American
