LIFE OF STAR

                                 LIFE OF A STAR

Initially when a star shines it converts all the hydrogen into helium when all the hydrogen in  the core gets used up, the  core of a star becomes hotter the helium starts converting into carbon. The outer area of the starts moving outwardly are the star becomes larger and larger the outer part of the star cools down and turns red from orange  and becomes hundred   times bigger than the orange star finally all the fuel in the core used up and no nuclear reaction takes place. The outer layers flies off into the space and the core becomes too small
