Stellar nebula: created by a cloud of dust. Every element heavier than helium was created in a star during fusion. Every element heavier than iron was created in the explosion of a star. Cloud of ash and dust coalesces and creates a big glob of material. The universe contains 2 basic elements: matter and energy. The scientific method provides a foundation to explore the cosmos.
