stargold




How gold is created in stars. Very interesting to realize, that stars can only burn up to Iron, going past that, into the fusion of Iron with more protons requires energy, so Iron is the heaviest thing that can be produce by nuclear fusion in a star.

So, how about elements more heavy than that, like gold?

Well, there are lots of different theories about that, a couple of them talk about processes in Supernova.

And how about the really heavy ones, like uranium?
