It is balanced by radiation pressure, and gas pressure.
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
A star maintains equilibrium during the main sequence because the inward force of gravity is balanced by the outward pressure from nuclear fusion in its core. This balance between gravity and radiation pressure prevents the star from collapsing or expanding significantly during this phase.
gravity
The force that pulls the material of a nuclear explosion back into a star is gravity. Gravity is the attractive force between objects with mass, and in the case of a star, it is the force that keeps the star's material gravitationally bound together despite the energy released in a nuclear explosion.

Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
In a star, the force of gravity is trying to collapse the star inward, while the pressure from nuclear fusion in the core creates an outward force, resisting the gravitational collapse. These two forces are balanced in a stable star, leading to a state of equilibrium.
In the case of a star (that is not actually going nova or supernova) they are balanced.
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
A star maintains equilibrium during the main sequence because the inward force of gravity is balanced by the outward pressure from nuclear fusion in its core. This balance between gravity and radiation pressure prevents the star from collapsing or expanding significantly during this phase.

Gravity is the force that causes stars to be created
Inside a star, there are two opposing forces at play: gravity tries to pull the stellar material inward, compressing it, while the force of nuclear fusion in the star's core pushes outward, generating energy and counteracting gravity to maintain the star's stability. These forces must balance each other for the star to remain in a state of equilibrium.
The opposite force of gravity is the electromagnetic force. This force is responsible for interactions between charged particles such as electrons and protons, and it can either attract or repel these particles depending on their charges.
