Gases from a dead star gather and contract statement describes the formation of a nebula.
<u>Option: D</u>
<u>Explanation:</u>
- A nebula is a massive cloud of spatially dust and gas. Many nebulae derive from the gas and dust pushed out by a dying star's eruption, like a supernova. Other nebulae are environments where the formation of new stars begins.
- Five forms of cloudy or nebulous celestial bodies are planetary nebulae, emission nebulae, transparent nebulae, supernova remnants and dark nebulae.
- The He and H are predominantly responsible for dust and gases, which are widespread but gravity can begin to pull around each other clusters of dust and gas gradually.
- As these clusters grow bigger and bigger, their gravity becomes better and better. The clump of dusts and gases finally becomes so heavy that it drops from its own gravity.
