how gold is formed

May 18, 2015· Gold isn’t truly formed—at least, not on Earth. Gold Comes FromOuter Space. Gold, the shiny yellow metal prized for its beauty and malleability and used in many different industries, is actually created inside massive stars when they explode into a supernova. Of course, after a star supernovas and forms gold, the precious metal has to travel to Earth in some way.
