1. The power of stars

2.  How stars obtain their energy  Two hydrogen atoms are smashed together at very high velocities  Nuclear fusion occurs at the center of all stars  Nuclear fusion gives universe energy  Other energies originate from this process

3.  Gives stars the ability to illuminate, to emit light  Example of Fusion as original energy  The gasoline to power your car comes from petroleum which is deposited in the ground millions of years ago as microorganisms.  The microorganisms got their energy from sunlight which in turn, the sun gets its energy from nuclear fusion

4.  High pressure in core of star  High density in core  High temperatures in core  A star must have all of these properties for the nuclear fusion process to work

5.  Not all stars posses the ability for nuclear fusion to occur in their centers  White or black dwarfs do not have this ability  The fuel for fusion is the lightest gas in the universe, Hydrogen

6.  Main fuel for nuclear fusion is hydrogen  Can use other isotopes of hydrogen such as tritium and deuterium  As a star runs out of hydrogen as fuel it starts using bigger elements like helium and lithium as fuel  Becomes red giant  When it runs out of fuel it either goes super nova or becomes a white dwarf depending on size of star

7.  Main problem is finding a material that can withstand extreme temperatures of a fusion reaction  A fusion reactor uses very powerful magnets to contain the fusion plasma  Scientists say they may be able to use nuclear fusion as a commercial energy source by 2030
