This describes a nebula, which is a vast cloud of gas and dust in space where stars are born. The gases and dust within a nebula are the raw materials that eventually come together under gravity to form new stars.
Roughly 1-2% of the solar nebula's mass consisted of rocky material. The majority of the nebula's mass was composed of hydrogen and helium, with smaller amounts of other elements like carbon, oxygen, and nitrogen. These rocky materials eventually accumulated to form the terrestrial planets in our solar system.
The Orion Nebula is called a star nursery because it is a region within our galaxy where new stars are actively forming. The nebula is a giant cloud of gas and dust where gravity causes these materials to come together and eventually form new stars. This process of star formation resembles a nursery where new stars are born.
A nebula of high density contains mostly gas and dust particles. As gravity causes these particles to clump together, they can eventually form stars or other celestial bodies. High-density nebulae are often stellar nurseries where new stars are born.
When two or more materials combine chemically, they from a substance. When two or more materials combine and they do not react with each other, they form a mixture.
gravitational pull of nebula materials on each other
Reactants are the starting materials of a reaction. Reactants combine to form the products.
When two or more materials combine chemically, they from a substance. When two or more materials combine and they do not react with each other, they form a mixture.
They form a compound.

A compound is formed when two or more materials chemically combine. If two materials combine physically, it is known as a mixture.
Two or more materials are put together they form a mixture if they do not react to form a compound.

protostar or nebula
A cloud of dust and gas where a star is born is called a stellar nursery or a nebula. These clouds are made up of materials like hydrogen and helium that gradually collapse under gravity to form new stars. Examples include the Orion Nebula and the Eagle Nebula.
