When Dead Stars collided,Earth got Gold:Scientists

New observations confirm that colliding neutron stars produce short gamma-ray bursts. Such collisions produce rare heavy elements, including gold.

Gold price may be falling or rising,an old question agitating the minds of the scientists has been -How this precious metal was formed on Earth.

Now scientists have reasons to believe that “unlike elements like carbon or iron, it cannot be created within a star.”

“Instead, it must be born in a more cataclysmic event — like one that occurred last month known as a short gamma-ray burst (GRB). Observations of this GRB provide evidence that it resulted from the collision of two neutron stars — the dead cores of stars that previously exploded as supernovae. Moreover, a unique glow that persisted for days at the GRB location potentially signifies the creation of substantial amounts of heavy elements — including gold”,says an article in the Science Daily.

This article quotes the lead author Edo Berger of the Harvard-Smithsonian Center for Astrophysics (CfA) saying this:”We estimate that the amount of gold produced and ejected during the merger of the two neutron stars may be as large as 10 moon masses — quite a lot of bling!”
