The life cycle of a star

• Nebula — gets pulled together by it's own gravity
  
• This starts a process called nuclear fusion (hydrogen turns into helium)

• (regular sized star) Red giant — white dwarf — black dwarf (invisible)
• (massive star) Super red giant — supernova — neutron star / black hole
