The origin of gold has long puzzled scientists from around the globe, and perhaps a group of scientists from a Chinese observatory has made a breakthrough. A macronova from gamma-ray bursts discovered by the Chinese team on Tuesday, June 16, may very well help explain how gold and silver came to be.
The gamma burst, called GRB060614, might hold the secret of how elements such as gold and silver came to existence.
Researchers from the Italian INAF/Brera Astronomical Observatory, Purple Mountain Observatory, and Israeli Hebrew University have all analyzed the date from the gamma burst, and in their studies, found the a macronova, posited to be the source of heavy elements.
According to the Chinese team, the discovery of the second macronova presents a chance for scientists to explore the beginnings of precious heavy metals like gold and silver. Aside from unlocking the age-old mystery, the macronova can also provide scientists a glimpse on the categorization of gamma-ray bursts.
Gamma-ray bursts, which are electromagnetic events associated with energy-filled explosions, are categorized as short and long depending on the duration of the burst. Some gamma-ray bursts, however, exhibit peculiar characteristics. For example, a 2006 study led to the discovery of long bursts that showcase features of short bursts. The gamma burst GRB060614 is one such case.
Macronova, on the other hand, is a product of a merger between a neutron star and a black hole or two neutron stars. Macronova is also known as an r-process supernova.
The Chinese team of researchers said that the discovery of the macronova in GRB060614 highly suggests that the burst came from a merged stellar-mass black hole and neutron star.
