Gravitational force pulls gas and dust particles together to form a nebula, while the outward pressure from gas particles pushing against each other (thermal pressure) prevents the nebula from collapsing under gravity. These two forces work together to stabilize a nebula.

Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
The force of gravity pulls matter inward, while the force of thermal pressure (from the heat of the gas) pushes matter outward. When these two forces are balanced, a nebula can remain stable without collapsing or expanding.
In a nebula, gravitational forces act to pull the gas and dust inward, while thermal pressure, generated by the heat from the particles and radiation from nearby stars, acts outward to counterbalance this gravitational pull. The balance between these two forces prevents the nebula from collapsing under its own gravity, allowing it to maintain its structure until conditions change, potentially leading to star formation.
Two forces that act on particles inside a nebula are gravity, which pulls particles together to form new stars and solar systems, and radiation pressure, which pushes particles apart due to the energy emitted by hot stars within the nebula. These forces must be balanced for a nebula to maintain its structure and not collapse or dissipate.

In a nebula, gravity and thermal pressure are two opposing forces that maintain balance. Gravity pulls the gas and dust inward, attempting to collapse the nebula, while thermal pressure, generated by the heat from the gas particles and any ongoing star formation, pushes outward. This equilibrium allows the nebula to remain stable for extended periods, preventing it from collapsing into a star or other celestial body. When these forces become unbalanced, it can lead to the formation of stars or other structures within the nebula.

The main forces acting on a nebula are gravity, which causes the nebula to collapse and form stars, and radiation pressure, which can push material away from the forming stars. Additionally, magnetic fields can play a role in shaping the structure and dynamics of a nebula.
The names of two nebulae are the Orion Nebula and the Crab Nebula.

There is no such thing as a nebula star.
