May 18, 2015· Gold Comes FromOuter Space Gold, theshiny 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.
Heat raging inside the universe’s early stars fused lighter elements together, such as hydrogen and helium. Over time, this fusion process created new elements like carbon and nitrogen. When those stars exploded, thecelestialevent provided the energy peak required to form gold.Get Price

Gold often occurs infree elemental (native) form, asnuggets or grains, inrocks, inveins, and inalluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).Get Price

During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals -- such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.Get Price
In fact, most scientists believe that gold came to earth from outer space -in large meteorites that struck the planet millions of years ago. By studying ancient rock samples with high-precision instruments, scientists have found evidence that accessible gold (that being mined), arrived via asteroids when the earth was still fairly young.Get Price
Mediterranean deep waters contain a slightly higher concentration of gold, which is attributed to wind-blown dust and rivers which also contain trace amounts of gold. Based on the samples taken from various bodies of water around the world, it is estimated …Get Price

Instead, most scientists now believe that gold actually came to earth from outer space in large meteorites that have struck the planet over billions of years. In fact, most of the gold on Earth is actually located in its core where its heavy properties caused it to sink over time. The gold that is found near the surface comes from relatively recent strikes of meteors that contained a considerable amount of gold.Get Price
