Prof. Brian Cox provides a great explanation in episode 2 of his excellent TV series 'Wonders of The Universe'.
In short, many elements can only be created in the extreme conditions which exist within stars as they burn all their internal fuel and gradually 'die'. As they die, massive changes take place within stars, creating the conditions which are required to create different types of elements.

No, iron is not the heaviest element made in massive stars. Massive stars produce elements through nuclear fusion in their cores, creating heavier elements than iron, such as lead, gold, and uranium. Iron is often referred to as the endpoint of nuclear fusion in massive stars because the energy required to fuse iron exceeds the energy output of the reaction.
its called a super nova.
What I have learned about massive stars is...
Hydrogen, helium, and carbon fuel are found in more massive stars. The diameter of more massive stars is bigger. Helium is found in greater abundance in more massive stars. The weight of more massive stars is greater.

Simply put, massive stars come from massive clouds called neblulae.
These are called ellipitical galaxies

The massive stars turn into gas
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
Those stars are called brown dwarves.
What I have learned about massive stars is...
Massive stars are most likely to explode faster than smaller stars.
