How are stars born?

Star are a compact of clouds of dust as we know for now but how are they born is a gigantic process with a formative duration of hundreds of years for the formation of a proper star. Before becoming a star, there are particles of dust which keep floating within every galaxy. These are the potential star particles which under immense pressure and duration will change into a fully adult star illuminating light. Speaking of which, one such example is the Orion Nebula. The dust particles have turbulence from within due to which the outer particles of the cloud starts to collapse under to its own gravitational force. These clouds may distribute into multiple potential star particles, forming a few number of stars. 

 As the cloud starts to collapse into its core, as it does, it starts to heat up resulting in high temperatures, radiation and sputtering light. It may take hundreds to thousands of years to form a proper adult star from its initial dusty cloud form.

A lifetime of a star can be a million or billion years till it collapses and give way to new star by providing materials for its formation. Stars have multiple gases spinning around them among which hydrogen is a principal element as it converts into helium in the interiors, providing the propellant for its light, also the flow of energy from interior to exterior prevent the star from collapsing under it’s own weight and pressure.

The life span of stars depends on the mass  and heat produced by stars. The smaller the star, longer the life span and on the contrary bigger stars have a smaller life span. Eg. the Red Dwarfs are the smallest stars in the universe with very low temperature, mass and light but has a life expectancy 10 billion years or more and are the populated among stars. On the other hand, the Hypergiants are the stars with the largest masses, temperature and emitting light thousands of time more than our Sun. But have a life expectancy of only a few million years. They are also believed to be numerous in number in the initial times of the universe but currently are very few in number, also pointing to its shorter lifespan and might have become sources to multiples of new stars.
