Introduction To Neutron Stars: https://www.astro.umd.edu/~miller/nstar.html “Neutron stars are the collapsed cores of some massive stars. They pack roughly the mass of our Sun into a region the size of a city." Neutron Stars: Definition & Facts: http://www.space.com/22180-neutron-stars.html “Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun. Born from the explosive death of another, larger stars, these tiny objects pack quite a punch." Earth's Gold May Come From Collisions of Dead Stars: http://www.space.com/21995-gold-origins-neutron-star-collisions.html “All of the gold on Earth might have come from cosmic crashes between superdense dead stars, new research suggests. The origin of the universe's gold is mysterious, since it's not formed within stars like lighter elements such as carbon and iron.” The Surprising Origin Of Earth’s Gold: http://www.popsci.com/science/article/2013-07/colliding-dead-stars-created-earths-gold “Pirates have hunted it. Monarchs have exploited it. Jewelers have sold it. But where did gold come from? Research by the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that the Earth's supply of gold originated from collisions of dead stars."

Asteroids May Have Brought Precious Metals to Earth: http://www.livescience.com/15938-earth-precious-metals-space-origin.html “The precious metals that we see on Earth today may be largely heavenly in nature, coming from the sky billions of years ago, scientists now find."
