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.
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.
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.

The names of two nebulae are the Orion Nebula and the Crab Nebula.

There is no such thing as a nebula star.

Two well-known nebulae are the Orion Nebula (Messier 42) and the Crab Nebula (Messier 1). The Orion Nebula is a diffuse cloud in the constellation Orion, visible to the naked eye, while the Crab Nebula is a remnant of a supernova explosion observed in the year 1054.
