- Black Dwarf
- White Dwarf

- Supernova
- Black Hole

- Supernova
- Red giant star
- Main sequence star, like sun
- Fusion in stars
- Nuclear fusion involves two atomic nuclei joining to make a large nucleus and energy is released when this happens.
- A hydrogen 1 and a hydrogen 2 react to form helium 3
- The temperature and pressure allow nuclear fusion to happen in stars. Stars have enough hydrogen to last for billions of years.
- Once hydrogen runs out, more substances react up to iron as this is an endothermic reaction. Other elements are released in supanovas
- Stars form when dust and gas clump together because of gravitational forces
- Gases create a protostar
