The third stage in the life cycle of a star is the main sequence stage, where a star fuses hydrogen into helium in its core. During this stage, stars like our Sun are stable and shine steadily due to the balance between gravitational forces pulling inward and nuclear fusion pushing outward. This stage can last for billions of years, depending on the mass of the star.
A star enters its third stage, known as the red giant phase, when it exhausts the hydrogen fuel in its core and starts fusing helium into heavier elements. During this phase, the star expands and becomes much larger in size.
Small intestine.. your welcome Gradpoint users.
After the main sequence stage, a star like the sun will enter the red giant phase where its core contracts and the outer layers expand. This is followed by the helium fusion stage where the star burns helium in its core. Ultimately, the fate of a star depends on its mass, which determines if it will become a white dwarf, neutron star, or black hole.
Third Stage was created in 1980.

It's generally accepted that a star has four stages in it's life.Birth - When it is createdMain Sequence - Where it converts hydrogen into energy.Maturity - When it has used up all of it's hydrogen.andStellar Remnants: - What's left after maturity.See related questions for more details.

People can enter and the stage by walking to the far left and far right of the stage. There are also stairs that lead from the stage to the audience.
the fourth stage of a star is "supergiant" and its also the hottest stage
