Indeed. Iron is the end state of nuclear fusion in stars since after Iron-56, energy is consumed. Depending on the mass of the star, any number of things can happen at this point. Complete core collapse into a neutron star or black hole. Or a pair-instability event may happen where the resultant explosion is more powerful than the gravity binding everything together - leaving nothing behind. Not even a black hole. (Note, these are exceeding rare events in the universe, at least with our current understanding of it)

 

So yup, everything beyond Iron itself, is made in the supernova explosion itself, or in the core of the star before the explosion (and then spewed into space in the explosion).

 

Man I love this stuff.

Gold can also be created by the ancient Alchemy -- a lost art.

 

 

I liked that episode of Fairy Tale Theater too.   :whistle:
