Stars are hot chunks of gas. They are held together by their own gravity. The closest star to the earth is the Sun. They give out light of their own because of atomic responses.

What are the phases in the Life Cycle of a Star?

The existence cycle of a star is dictated by its mass. The bigger the mass of a star the shorter will be its life cycle. The life of a star ranges from two or three million years to a billion years, contingent upon the mass.

It is accepted that stars are conceived from crumbling thick dust storms and gas found in winding systems. These mists are called sub-atomic mists or nebulae, and are comprised of 97% hydrogen and 3% helium.

At the point when the cloud crumples under its very own gravitational power, it breaks separated and brings about the development of a thick circle called a Protostar.

These protostars are thick collections of residue and gas which have not started to create light. As the mass of each protostar increments so does its gravity, pressing the center of the protostar harder.

As the stars grow, they become less brilliant, because of the center coming up short on hydrogen and afterward helium. At that point the star enters the primary arrangement or grown-up stage. A star stays in this stage for most part of its lifetime.

A star leaves its principle arrangement eliminate when it runs of hydrogen and starts intertwining helium and different components.

Diminish little stars are called red diminutive people. The combination of hydrogen in them, happens at an extremely moderate rate and they can stay in the primary arrangement for billions of years.

The low mass stars like our sun grow and become red monsters. This red monster is a huge star that is brilliant with a cool surface. This is shaped when the star comes up short on hydrogen. They are splendid in light of the fact that they are so enormous.

Stars pass on in blasts called supernova. Supernova prompts the center packing into a neutron star or a dark opening.
