The balance of forces that keeps a star from collapsing is called hydrostatic equilibrium. This equilibrium occurs when the outward pressure generated by nuclear fusion in the star's core balances the inward gravitational force trying to collapse the star. If these forces are not balanced, the star may either contract under gravity or expand until a new equilibrium is reached.

Dynamic equilibrium.
The sun stays in space due to a delicate balance between two forces: gravity pulling the sun towards the center of its mass, and the outward pressure created by nuclear fusion reactions happening in its core. This balance keeps the sun stable and prevents it from collapsing or drifting away.
The sun is held in place by its own gravity, which creates a delicate balance between the outward pressure from nuclear fusion in its core and the inward pull of gravity. This balance keeps the sun stable and prevents it from expanding or collapsing.
The sun's immense gravitational pull created by its mass keeps it from falling. The gravitational force pulls the sun's gases and radiation inward, creating a balance with the outward pressure caused by nuclear fusion reactions in its core. This balance keeps the sun stable and prevents it from collapsing under its own weight.

The uterus keeps the trachea from collapsing in a fetal pig.
Like a camera has a case, the eye is surrounded by tissues and are filled with fluid called "humours" to keep it from collapsing.
Its cytoplasm.
cytoplasm
Atoms do not collapse because of the balance between the electromagnetic force, which repels the positively charged protons in the nucleus, and the strong nuclear force, which holds the nucleus together. This balance keeps the atom stable and prevents it from collapsing.
The sun is held in place by its own gravity, which creates a delicate balance between the outward pressure from nuclear fusion in its core and the inward pull of gravity. This balance keeps the sun stable and prevents it from expanding or collapsing.
"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."

The trachea has a series of cartilage rings that prevent it from collapsing.
