Stellar nurseries are vast clouds of gas and dust in space where new stars are born. These regions, often found in galaxies, contain the necessary materials for star formation, including hydrogen and helium. When parts of these clouds collapse under their own gravity, they create dense cores that eventually ignite nuclear fusion, leading to the birth of a star. These nurseries are often associated with bright, colorful nebulae, such as the Orion Nebula. As stars form, they can also trigger the formation of surrounding stars, creating clusters. Stellar nurseries play a crucial role in the life cycle of galaxies, contributing to the ongoing process of star formation.
