Why do stars form in nebulae?

Stars form in nebulae because these regions contain dense clouds of gas and dust, providing the raw materials for star formation. When parts of the nebula collapse under their own gravity, they form protostars, which eventually ignite nuclear fusion in their cores. The Orion Nebula is a well-known stellar nursery where active star formation can be observed. Nebulae are essential to the life cycle of stars and contribute to the recycling of elements across the universe. Their striking colours and shapes make them some of the most photographed objects in space.
