While reading this article I found out that no one knows for sure where gold originated from. Some astronomers have recently suggested that neutron-heavy metals like gold are easily made in rare neutro-rich explosions. Since many other types of precious metals are thought to have come from explosions, it is possible that gold is suvenir from an earlier explosion in our galaxy.
I learned that a supernova explosion is one of the most powerful of its kind. This explosion occurs if the star is very large and it collapses and releases a lot of energy. After the star collapses the result is usually a rapidly moving neutron star that is observed many years later.
