Question

Quizplus · Accepted Answer

Stars spend the majority of their lives in the main sequence phase, during which they consume hydrogen in their cores to forge heavier elements like helium through nuclear fusion, releasing a tremendous amount of energy in the process. This energy release is what powers the star and produces the light and heat it emits.
