What cosmic structures are nebulae described as the fundamental building blocks for?

Answer

Stars, planets, and galaxies

Nebulae, composed of gas and dust drifting through space, are characterized as the essential raw materials from which larger cosmic structures form. Specifically, these interstellar clouds serve as the foundational substance leading to the creation of stars, the subsequent formation of solar systems including planets, and ultimately contribute to the organization of galaxies. Their evolution, driven by gravitational contraction, is central to the structure of the observable universe.
