Well the heaviest a star can get is Iron. But then when it went
  Supernovae, SOME of the elements were created from the pressure
  waves. But not all of them. Some of the other elements were
  created when it struck a massive molecular gas cloud. At least
  that's what I remember. After that, static electricity started
  collecting things together. When they were big enough, gravity
  took over, and stuff was spinning... spinning, spinning.. and
  the rest is the animations we saw in grade school I think.
