The life cycle of a star in order (rearrange the steps below.) In the nebula, compact pockets of interstellar gas clouds of hydrogen and dust collapse in themselves under their own weight. Nuclear fusion begins causing the star to glow as Hydrogen is changed to Helium. A supernova occurs. A neutron star forms, if it is a massive star and black hole forms, if it is a supermassive star. Iron, which acts as an energy sponge, forms within the star. A red giant forms when the star's hydrogen amount drops. A main sequence star forms, which last 20 million to 80 billion years depending on mass.
