Is it true that Gold is rare in the universe?

Not surprisingly, gold is called precious metals, rare materials, and high value. Recent research by the Harvard-Smithsonian Center for Astrophysics in the U.S. found that the gold is not widely found in the universe. Not all planets have them.

Then, from where the gold come from? Unlike the other elements, such as carbon or iron, gold can not be formed in the star. Instead, the gold should be born through a more powerful way known as short Gamma-ray bursts (GRBs).

This phenomenon suggests that the bursts of gold produced from the collision of two neutron stars, the core of the dead star that exploded as a supernova before. In addition, the unique light emanating days in bursts indicate the location of the majority of the creation of heavy elements, including gold. "The amount of gold produced during the merger of two neutron stars may be as much as ten times the mass of the moon," said the study leader, Edo Berger.

Gamma-ray bursts are flashes of light that has high energy and is derived from the full blast of energy. Explosion is most commonly found in the distant universe. Berger and his team studied GRB 130603B, nearby explosions seen to date. The distance is about 3.9 billion light years from Earth.

Long gamma-ray bursts depends on how long it lasts flashes of gamma rays. GRB 130603B was detected by the Swift, a satellite of the National Aeronautics and Space Administration (NASA) on June 3, 2013 for two tenths of a second.

Berger and his team calculated that about one-hundredth of a solar mass released by gamma-ray bursts, some of which are gold. According to him, all the gold in the universe derived from gamma-ray bursts. Jewelry that is in the earth, he said, comes from the star. *** [EKA | FROM VARIOUS SOURCES | SPACE | SCIENCEDAILY | MAHARDIKA SATRIA HADI | KORAN TEMPO 4296]
