  7. Protostar

  8. Nuclear Fusion
    When it is so hot that when atoms hit each other the become other atoms
  9. Photosphere

  10. Sunspot
    A darker, cooler area on the suns photosphere
  11. Solar Wind

  17. Spectral lines
    Distinct lines that help to define what atoms and molecules are within that spectrum.
  18. H-R Diagram
    A way of graphing a stars spectrum type against its luminosity
  19. Main Sequence
    Where a star stays for most of its life before evolving and dying, either a low, intermediate or high mass star.
  20. White Dwarf
    The stage where a star slowly cools down and fades away
  21. Supernova
    When a star explodes at the end of its life
  22. Neutron Star
    A star created by a supernova that is so hot only protons and electrons essentially melt themselves into neutrons
  23. How low mass stars evolve
    Gravity compresses into white dwarfs and eventually fade away
  24. Black hole
    a patch of space that has mass but no volume
  25. How do intermediate mass stars evolve
    They become red giants that eventually explode in a super nova and remain as nebula
  26. Evolution of high mass stars
    High mass stars become red supergiants before either condensing into a neutron star or exploding into a black hole
