Billions of tons of pressure and heat due to the fusing atoms of Hydrogen and Helium. It does vary from star to star but it is unlivable for anything in the Universe. Not even the Atoms inside survive they get fused together to become a hydrogen helium compound that is not possible to replicate anywhere but the star itself.
The presence of white fuzz inside an apple core is caused by mold growth. Mold spores can land on the apple and grow in the moist environment of the core, leading to the formation of the white fuzz.
The inside of a star consists of different layers, including a core where nuclear fusion reactions occur. As you move outward from the core, you encounter layers of hydrogen and helium undergoing fusion, followed by layers of gases in different states due to temperature and pressure variations. The outermost layer is the star's atmosphere, where gases are less dense and extend into space.
Inside a supergiant star, the core is primarily composed of elements such as hydrogen and helium, undergoing nuclear fusion processes. As the star evolves, heavier elements like carbon, oxygen, and iron form in the core through successive fusion stages. The immense pressure and temperature in the core drive these fusion reactions, eventually leading to the star's collapse and possible supernova explosion once iron is produced.
The core of a star is located inside the star in a region where the temperature and pressures are sufficient to ignite nuclear fusion, converting atoms of hydrogen into helium, and releasing a tremendous amount of heat.
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
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.

During the main sequence stage, a star's core fuses hydrogen into helium, converting mass into energy. As the star evolves into later stages, it begins fusing heavier elements and creating new elements. This process changes the elemental composition of the star's core, ultimately influencing its mass.
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.
Temperatures in the star's core can reach 3x109 K.
