Stars, planets, solar systems, many objects in space can start as a large unstructured nebula of gas and dust, which can coalesce into massive objects under gravitational influence.
Star formation starts in a nebula.
A nebula begins to contract due to gravitational forces overcoming the pressure from its internal gas and dust. As the material within the nebula begins to clump together, the gravitational attraction increases, leading to further contraction. This process can be triggered by external factors such as shock waves from nearby supernovae or collisions with other clouds, which can compress the nebula and initiate star formation. As the nebula contracts, it can lead to the formation of stars and planetary systems.
A solar nebula begins to form when a cloud of gas and dust in space collapses under its own gravity. This collapse can be triggered by a nearby supernova explosion, a shockwave from a passing star, or other disturbances in the interstellar medium.
A nebula comes first; it is a large cloud of gas and dust in space. Under the influence of gravity, regions within the nebula can collapse to form a protostar. As the material falls inward, the protostar heats up and begins the process of nuclear fusion, eventually leading to the formation of a star.
After a nebula, the next stage in the life cycle of a star is usually a protostar, where gravity causes the gas and dust within the nebula to begin collapsing and forming a dense core. Following this stage, the protostar may evolve into a main sequence star, where nuclear fusion begins in its core and it enters a stable period of energy production.
