- Lives of Stars
- Dust and Gas particles
- Mainly Hydrogen
- these collapse due to gravity -spiral in and become concentrated, form:
- Protostar
- Hot ball of gas
- name for "star to be"
- Main Sequence Star
- Enters a long stable period
- heat from nuclear fission provides outward force
- this balances the force of gravity-which pulls everything in
- star maintains energy due to the vast amount of HYDROGEN left to react
- when Hydrgen runs out, star swells into:
- Red Supergiant
- undergoes more fusion=heavier elements formed
- through nuclear fusion
- expand and contract several times
- explode into:
- Supernova
- explode into:
- heavier elements ejected into universe
- can form planets/stars
- Neutron Star
- very dense core
- Black hole
- if the star is big enough
- undergoes more fusion=heavier elements formed
- Red Giant
- Main Sequence Star

- Red Giant
- stars the size of sun
- these become unstable= ejects outer layer of dust&gas as PLANETARY NEBULA
- Turn into hot, dense, solid core
- White Dwarf
- cools into:
- Black Dwarf
- Disappears
- White Dwarf
- Turn into hot, dense, solid core
- White Dwarf
- cools into:
- Black Dwarf
- Disappears
- Red Supergiant
- heavier elements can also be formed (gold, iron, etc)
- when Hydrgen runs out, star swells into:
- star maintains energy due to the vast amount of HYDROGEN left to react
- this balances the force of gravity-which pulls everything in
- heat from nuclear fission provides outward force
- Give out a lot of light and heat
- smaller objects can also be formed-these are planets
- Enters a long stable period

- Big Bang
- all the energy in the world today was created here( during the big bang)
- Dust and Gas particles
- A start is born
- Hydrogen nuclei react with eachother-FUSE- to form HELIUM
