24 Karat Gold
The fascination with gold has been constant over the centuries. This is not just because of its beauty and rarity, but for its mysterious history. Although ancient civilizations believed gold to be a gift by gods, modern science has revealed that its real origins lie far beyond our planet. A ground-breaking study has provided a new understanding of the cosmic processes that led to the development of gold, reversing old beliefs and providing fresh insight into the universe's most violent events.
Gold is a heavy metal, which means it has more neutrons and protons than iron, which is the most heavy element formed through the normal stellar fusion. This begs the question of how gold came into existence? For a long time researchers believed that supernovae - the rapid deaths of massive stars were the main sources of the gold. But, new research has shown that other cosmic events also contribute to the production of gold.
Supernovae happen in the event that a huge star burns out its nuclear fuel and collapses due to gravity. This results in a catastrophic explosion. In this course of explosion, extreme heat and pressure trigger nuclear reactions that produce elements heavier than iron, such as gold. These elements get dispersed into space and enrich the interstellar medium, bringing in the formation of new planets and stars.

A significant discovery changed our perception of the origins of gold in 2017. Astronomers witnessed the merging of two neutron stars, which are dense remnants of supernova eruptions, in the event GW170817. The collision produced gravitational waves and the radiation of electromagnetic waves, including gamma rays. A spectroscopic examination of the radiation from the event revealed the presence of heavy elements, such as platinum and gold. This proves the fact that mergers of neutron stars are an important source for these metals.
The r-process or the rapid neutron capture, has been believed to be the cause for the formation of these heavy metals. When a neutron star merge occurs, the massive gravity forces and the high temperatures create the conditions for the r-process. This leads to the creation of gold and the other heavier elements.

A new study has revealed an additional gold source that is not widely known - magnetar flares. Magnetars are a rare form of neutron star that has extremely powerful magnetic fields. Sometimes, they experience violent flares, also known as starquakes. This is when their fields become unstable. The flares could release huge quantities of energy and release neutron-rich matter into space. When the material cools, the r-process may occur and lead to the formation of heavy elements, such as gold.
This study suggests that a single magnetic flare could produce around two million billion kilograms of heavy elements. This could potentially account for around 10% of the platinum and gold in our galaxy. This discovery adds a new perspective to the understanding of cosmic processes that contribute to an abundance of gold in the universe.
When it gets formed in the cosmic sphere, gold must travel long distances before reaching Earth. The heavy elements created by neutron star mergers, supernovae and magnetar flares get scattered into the interstellar medium. This includes the dust and gas formed between stars. With time, these elements get incorporated into new star systems, including our Solar System.
The presence of gold on Earth shows the violent and energetic processes that took place billions of years ago. As the Solar System gets formed from a cloud of gas and dust, it inherits the heavy elements produced by these cosmic events. Through processes like the planetary differentiation process, volcanic activity and gold accumulated in the crust of Earth, and was eventually mined by humans.

The identification of gold production during magnetar flares was based on a combination of observations of gamma-rays, spectroscopic analysis and theoretical modeling. Through comparison of the energy output and the nuclear reactions that might occur during these events, scientists discovered the possibility of heavy elements synthesis.
Modern computational simulation models mimic these extreme conditions. This assists researchers to understand the behavior of neutrons under extreme radiation and magnetic pressure. With the improved technology for observation, mainly in the field of gamma-ray detection and gravitational wave astronomy, our ability to detect and study these cosmic events will improve.
Understanding the history of gold improves our understanding of stellar evolution and the synthesis of elements. We get to understand the dynamic processes that create our galaxy. This understanding underscores the interconnectedness between cosmic events and the physical structure that makes up our earth.
When we talk in a more philosophical sense, the realization that gold comes from some of the most intense and powerful events that occur in the universe gives a sense of awe and respect to the precious metal. It is a reminder of the immenseness and depth of the universe and our place in it.

The discovery offers new possibilities for further research on this topic. With the next generation of observatories like the James Webb Space Telescope, the Vera C. Rubin Observatory and improved gravitational wave detectors, such as LIGO's scheduled upgrades, scientists are expecting to see more neutron star mergers in the coming years.
Every new discovery will aid in improving models of nucleosynthesis. They will also deepen our knowledge about the r-process and help answer questions regarding the variety and frequency of the formation of heavy elements.
There is also a growing interest in studying the study of metal-poor stars. These are stellar bodies with extremely low quantities of heavier elements. By studying the structure of the stars scientists can identify when and how metals like gold first came into the beginning of our universe. This cosmic perspective on golds origin comes at a time when the new gold rules in India 2025 are also making headlines
