Meteorite diamond6/26/2023 ![]() Our solar system was believed to have started with proto-planets. This incredibly high pressure led to the belief that the meteorite is a part of a destroyed planet, which was a planetary "embryo", with the size of that between Mercury and Mars. The diamonds were formed by an intense pressure of about 20 GPa (giga-Pascals unit of pressure), which is close to the pressure seen 400 miles below Earth's surface, where the upper mantle transitions into the lower mantle. The materials in questions came from sharp shocks of temperature and pressure. They were also used as information to understand the long history of the element.Īccording to an extensive analysis, the researchers found that the diamonds contained chromite, phosphate and iron-nickel sulfides.Įvery bit of data converges into an important discovery, especially when it comes to the historical structure of the solar system. It is these characteristics that made the diamond extraordinary. The diamonds also contain tiny imperfections called inclusions. The size of the gems is much larger than any other meteorite diamond that has ever been found before. Ureilites are rich in diamonds, but scientists are still trying to understand the specific mechanisms that formed them. They found that it belonged to a rare category of meteorites known as ureilites. The M-types are made up of nickel-iron and are located in the middle region of the asteroid belt, where the circumstellar disc between the orbits of the planets Mars and Jupiter exists.įarhang Nabiei, a materials scientist at the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, and his colleagues, examined the contents of the rock for an extended period of time.The S-types, known as "stony", are metallic and contain silicate materials.It is estimated that the C-type can contain up to 22% water and have never reached temperatures above 50☌. These asteroids have a dark color and belong to a class with the most ancient objects in the solar system. The C-type is a unique category and consists of clay and silicate rocks.The three broad classes of asteroids are C-, S-, and M. ![]() The composition of the asteroids depends on their distance from the sun and the radius of the orbit. The largest asteroid is about 329 miles in diameter and each of these have irregular shapes. Scientists suggest that diamond fragments in the meteorite hailed from a long-lost planet. Inside the solar system, it is possible to find a lot of evidence that reveals the history of this part of our universe. It takes about 230 million years to make one complete orbit around the Milky Way, as the galaxy is 100,000 light years in diameter. The sun and the solar system orbit in the center of the Milky Way Galaxy. Our solar system is gravitationally-bound and contains the sun and bodies that orbit it, such as planets, asteroids, moons, comets, and meteorites. The study is published in Nature Communications. This is the first time in history that researchers have discovered fragments, as a remnant of a destroyed planet, from the early ages of our solar system. It is speculated that the rock arrived from a probably destroyed planet, that orbited our sun billions of years ago. New research suggests that these diamonds could have only formed within a planet that no longer exists, the long-lost planet.
