I want to know if you have institute or college that offers nursing programs, if so, what's the requirements.
As the gas falls together, it gets hot. A star forms when it is hot enough for nuclear reactions to start. This releases energy, and keeps the star hot. Gravity pulls the dust and gas together. During its 'main sequence' period of its life cycle, a star is stable because the forces [force: A push or a pull.The unit of force is the newton, 'N'. ] in it are balanced.The outward pressure from the expanding hot gases is balanced by the force of the starâs gravity. Our Sun is at this stable phase in its life.uring its 'main sequence' period of its life cycle, a star is stable because the forces [force: A push or a pull.

Generally stars spend most of their active lives travelling through the stage of stellar life-cycle known as the Main Sequence. I say 'active' life because the remnants of dead stars can persist more or less indefinitely, slowly fading into obscurity. I say 'generally' because even dead stars sometimes find ways to obtain new life
