Nebular Theory (Stars (Small Star (Our sun (Fuses Hydrogen into Helium…

- - - - Fuses Hydrogen into Helium
        
        Releases radiation
  - - - how hot
      - How bright
      - Length of life
      - Stars with more mass
        
        Hotter, brighter, shorter life
      - Stars with less mass
        
        Cooler, Dimmer, long life
  - - - Fuses helium into heavier elements
        
        Star expands
        
        Makes it cooler and larger
        
        Red in color
  - - - Star try's to combine carbon into heavier elements
        
        Gas expands away
        
        Leaves a hot glowing carbon core called a white dwarf
  - - - looses brightness
        
        Becomes a black dwarf
  - - - core will collapse into a black hole
        
        Strong gravity
        
        Very dense
  - - - Hydrogen and Helium
        
        Runs out of Hydrogen and Helium
        
        star expands and forms a Red supergiant
        
        Star only has iron left gravity will collapse it and it will explodes= supernova
- - - - Also heavier elements from collapsed stars
  - - - Nebula shrinks
        
        Begins to rotate
        
        Forms a disk shape
  - - - Becomes more dense
        
        Pressure and temp. go up
        
        Core temp
        
        Gets hot enough Nuclear fusion starts
        
        A star is formed
  - - - Clumps get larger and attract others
        
        Clumps form planets and moons
        
        Completes a Solar System
- - - - Stars, planets, and galaxies etc.
        
        All are parts to the universe
        
        All are made from the materials in a nebula
