- NEBULA - stars initially form from a cloud of dust and gas
- PROTOSTAR - gravity pulls the dust and gas together. The temp rises as the star gets denser and more particles collide. Hydrogen nuclei undergo nuclear fusion to form helium nuclei
- MAIN SEQUENCE STAR - stable period that lasts several billion years
- RED SUPERGIANT- if it is a large star. Fusion of helium + elements (up to iron) are formed
- SUPERNOVA - more fusion takes place. Heavy elements like iron formed. Eventually star explodes in a supernova
- NEUTRON STAR - very dense core of supernova
- BLACK HOLE - extremely large stars can form a black hole. So dense even light cannot escape
- SUPERNOVA - more fusion takes place. Heavy elements like iron formed. Eventually star explodes in a supernova
- RED GIANT - if it is a small star (like the sun). Fusion of helium + elements (up to iron) are formed
- WHITE DWARF - outer layer of dust is ejected, leaving a hot, dense solid core
- BLACK DWARF - as star cools down, it emits less energy + becomes a black dwarf
- WHITE DWARF - outer layer of dust is ejected, leaving a hot, dense solid core
- RED SUPERGIANT- if it is a large star. Fusion of helium + elements (up to iron) are formed
- MAIN SEQUENCE STAR - stable period that lasts several billion years
- PROTOSTAR - gravity pulls the dust and gas together. The temp rises as the star gets denser and more particles collide. Hydrogen nuclei undergo nuclear fusion to form helium nuclei
