The story of worlds extends far beyond the graceful gyrations of the Milky Way. The macrocosm is a vast cosmic shade, woven with a different array of worlds — from smooth ellipticals to chaotic irregulars, all shaped by graveness, cosmic forces, and dark matter’s unnoticeable hand. In this occasion, we trip into the different world types, the cataclysmic cotillion of combinations, and the important machines at their cores that drive their elaboration.
