Galactic structures refer to the large-scale organization and patterns of galaxies within the universe. This field of research aims to understand the distribution of galaxies, clusters of galaxies, and superclusters, as well as the physical processes driving their formation and evolution. Scientists study the structure of galaxies on various scales, from individual galaxies to the cosmic web of galaxy clusters spanning millions of light-years. By analyzing these structures, researchers gain insights into the fundamental properties of the universe and the processes that govern its overall structure and evolution.
