New research published late last month in the Journal of Planetary Science has found that exoplanets with the correct proportions of carbon and oxygen will be made mainly from diamond and natural compound silica.
“These exoplanets are unlike anything in our solar system,” lead author Harrison Allen-Sutter of Arizona State University’s School of Earth and Space Exploration said in a press release.
The discovery has come in the form of scientists, enabled by more and more information from recent space missions, able to put the pieces together and understand what planets look far beyond our Earth.
While the Earth’s diamond content is about 0.0001%, researchers believe that the exoplanets that surround the stars with a higher carbon-to-oxygen ratio are more carbon-rich and, assuming the presence of water, an excessive diamond – Heavy makeup can occur.
The science behind this hypothesis is extremely fine, but researchers were able to test their theory of what happens, while silicon carbide and water are sandwiched between diamonds at very high pressures. Complex experiments, which included laser heating and X-ray measurements, turned silicon carbide into diamonds, as well as silica.
Although they now have more evidence that diamonds are planets or at least may exist, scientists do not believe that such worlds are capable of sustaining life.
“Regardless of habit, this is an additional step in understanding and characterizing our ever-increasing and improved observations of exoplanets,” Allen-Sutter said. “The more we learn, the better we will be able to interpret new data from future missions, such as the James Webb Space Telescope and the Nancy Grace Roman Space Telescope, to understand the world beyond our own solar system.”
In 2012, astronomers believed that they had discovered a planet made of diamonds, and it was so close to our world that it was visible to the naked eye.
