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.
Star formation starts in a nebula.
A nebula develops into a solar system through the process of gravitational collapse. As the nebula contracts due to gravity, it starts to spin and flatten into a spinning disk. Within this disk, the material begins to clump together and form planetesimals, which eventually coalesce to form planets, moons, and other objects in the solar system.
Gravity is the force that holds matter in a nebula together. As the nebula contracts under its own gravity, the particles begin to clump together, eventually forming stars and other celestial bodies.
After a nebula contracts and its temperature increases, the gravitational forces cause the gas and dust to clump together, leading to the formation of a protostar. As the protostar continues to accumulate mass, its core temperature rises further, eventually reaching the point where nuclear fusion ignites. This marks the birth of a new star, which then begins to shine and can eventually evolve into different types of stars depending on its mass. The surrounding material may form a protoplanetary disk, potentially leading to the creation of planets.

begins to collapse under its own gravity due to a disturbance, such as a shockwave from a nearby supernova. As the nebula collapses, it heats up and the particles within it start to come together, initiating the formation of a protostar.
A star is born when a nebula, a vast cloud of gas and dust in space, undergoes gravitational collapse. As the nebula contracts, the material within it becomes denser, leading to increased temperatures and pressure at its core. Once the conditions are right, nuclear fusion ignites, marking the birth of a new star. This process illustrates the life cycle of stars, where stellar formation begins from the remnants of previous stars.
