This energy now generates a gravitational disruption in the molecular cloud. The cloud's center gains mass as it starts to collapse under its own gravity, causing hydrogen and helium to clump together. The gravitational force is increased by this increase in mass, drawing even more molecules and other particles from the environment.
A Protostar keeps drawing in additional molecules and heating up until the temperature and pressure are high enough for hydrogen atoms to start fusing together, creating helium and releasing heat, light, and radiation. This process called nuclear fusion.
Oh! Whose birthday is it, little girl?
So, let us explore the creation of a star and answer a burning hot question, “How was a star formed?”
HAHAHA! Well, unfortunately, we don’t know the exact date of a stars’ birthdays. However, we do know something about its birth and how it came into existence.
Stars radiate a great quantity of heat and light, resembling enormous balls of fire.
When this occurs, the outward force produced by heat and radiation precisely balances the inward force of gravity. These inward and outward forces maintain balance and thus, a star is born.
Stars do not form in a few seconds, minutes or hours. Star formation process is so slow that it can take millions of years.

Cold and Stable
A star begins its life inside enormous molecular clouds of gas and dust. These molecular clouds are also knownas nebulae or dark nebulae. They generally consist of molecules of hydrogen and helium, along with a few other particles. These molecular clouds are typically cold and stable. However, a molecular cloud may experience a shockwave or massive amount of energy from a nearby supernova explosion or galaxy collision.
