While searching for other habitable planets similar to Earth, he found “something strange”, different from everything seen in the solar system, as revealed by scientist Natalie Batalha, in charge of the Kepler space probe mission from NASA’s Space Research Center. America, according to the Russian news agency “Sputnik”.
What scientist Natalie revealed, is the preparation of a team of researchers at Arizona State University (ASU) and the University of Chicago with a new study published in The Planetary Science Journal.
The team discovered that some carbon-rich exoplanets, under the right conditions they are going through, could form asteroids of diamond and silica (silicon dioxide), according to the dailygalaxy newspaper, which specializes in space affairs.
Harrison Allen Sutter of Arizona State University for Exploration of Earth and Space, lead author of the study, noted that these planets “are not like anything in our solar system,” noting that the study indicates that when stars form in space and planets, they do so in a cloud of gas. Their composition is often the same, but stars that contain a low percentage of carbon to oxygen will form planets similar to Earth, and have a low percentage of diamond, silicon and oxides, with a ratio of, for example, 0.001% of the planet.
But exoplanets around stars with a high carbon to oxygen ratio, they are rich in carbon, and the study assumed that these carbon-rich exoplanets could turn into diamonds and silicates, if water (abundant in the universe) is present, which leads to the formation of a composition rich in diamonds.
To test this scientific hypothesis, the research team needed to simulate the inner part of the outer planets made of carbide using high heat and high pressure, the scientists used high pressure diamond anvil cells and dipped silicon carbide in water and exposed the sample to high pressure that simulates the conditions of outer space, and as they expected, With increasing temperature and pressure, silicon carbide reacted with water and turned into diamond and silica.
