When two neutron stars collide in space, gold and other metals heavier than iron are created. The collision of these ultra-dense, dead stars generates vibrations in spacetime itself. These ripples are referred to as gravitational waves. The collision also produces high-energy gamma-ray bursts and a flash of light (kilonova), both of which can be seen from great distances in space.
Throughout history, humans have fought and died for gold. Mines produce gold for us. On a grander scale, it is formed when huge stars collide. The formation of the highly sought-after precious metal is as violent as historical attempts to obtain it.
When two neutron stars collide in space, gold and other metals heavier than iron are created. The collision of these ultra-dense, dead stars generates vibrations in spacetime itself. These ripples are referred to as gravitational waves. The collision also produces high-energy gamma-ray bursts and a flash of light (kilonova), both of which can be seen from great distances in space.
The sole reported kilonova explosion was analyzed by a team of researchers from the Max Planck Institute for Gravitational Physics and the University of Potsdam. We took note of it in 2017.
According to the institute, the scientists employed modern technologies to investigate the signatures of this kilonova. Aside from what was recorded in 2017, further data from radio and X-ray observations of other stars was included. The results of a collision experiment conducted on Earth were also given.
Based on their research of the 2017 kilonova explosion, the researchers created a model. The model will aid in understanding the universe’s only known process for producing metals heavier than iron.
“Our new method will aid in the analysis of matter properties at extreme densities.” It will also help us better comprehend the expansion of the cosmos and how heavy metals are generated during neutron star mergers,” said Tim Dietrich, a Max Planck Institute scientist, as cited on the institute’s website earlier this month.
So, where has the gold gone?
When large stars die, the nuclear fusion process that powers them ceases. This results in the formation of an ultra-dense, neutron-rich star. When such stars collide, it is called a supernova. These free neutrons are released into space and caught up by atoms, resulting in the formation of very heavy elements that are outside the purview of the periodic table. These elements are unstable and slowly degrade into heavier elements than iron. Gold is one of these metals.
That gold ring you’re wearing is genuine stardust!
