Golden showers
Only the first 25 elements past hydrogen are produced in stars. All the other naturally occurring elements were made from supernova events.
That's what we used to think, until recently. It has been known for a while that the r-process in supernovae can't account for the quantities of elements past iron that we see. Colliding neutron stars are responsible. See this highly respected scientific journal for a few more details.
