How do very massive stars end their lives?
consumed by black hole
become super novas
explode
become red supergiants
A more massive star ends its life in a more dramatic way. Very massive stars become red supergiants . Unlike a red giant, when all the helium in a red supergiant is gone, fusion continues. Lighter atoms fuse into heavier atoms up to iron atoms. Creating elements heavier than iron through fusion uses more energy than it produces. For this reason, stars do not ordinarily form any heavier elements. When there are no more elements for the star to fuse, the core succumbs to gravity and collapses.
