Schematic illustration of the hierarchical structure of the Universe, from a galaxy group (a collection of galaxies) to an individual galaxy and the supermassive black hole at its center. Although a black hole is more than 100 million times smaller than the radius of its host galaxy, it plays a crucial role in the galaxy's central region.
