Question: how are stars created

Daniel Parsons answered on 12 Nov 2014:

Stars are formed when giant clouds of gas clump together in space and then gravity begins to pull all the clumps toward each other. These clouds of gas are made of mostly hydrogen and some helium. Once gravity pulls the gas together in large volumes ….and pulls them together strongly enough, nuclear fusion will begin to occur in the core of the star. This is where molecules of gas are fused together releasing energy. This is the reaction and energy that a star uses to shine brightly. This process will continue throughout the life of the star, until all of the fuel is used up.
