Yes very interesting. Gold was originally formed within supernovae, which is a sure sign that our planet is formed from molecules that have been through at least one or two supernovae already. Another fund gold fact, the reason gold appears in "veins" is that it's actually big blobs, but over time water runs through the blob, dragging along little bits of dust with it down the same channel. Those little bits of dust build up and become veins of gold.
