Stellar evolution encompasses the life of a star from its formation until its end. Many astronomers believe that the birthplaces of a star are those molecular clouds of gas located in the spiral arms of galaxies. The life of a star begins when protostars are created from the collapsed dense regions of gas clouds. At […]
