US scientists slotxo have revealed evidence that some planets in the universe may be formed from minerals that make up diamonds. The researchers aimed to study planets that are primarily outside the solar system.
Some of the carbon-rich exoplanets are likely to have optimum conditions for producing and storing diamonds, researchers at Arizona State University who have studied diamond-rich planets. High, that is, some planets may be formed from silica Which is a mineral found on earth in the form of sand and quartz etc.

Harrison Allen-Sutter, researcher at Arizona State University, Department of Earth and Space Exploration. The head of the study said these exoplanets are not like any other. In the solar system
In a research study recently published in The Planetary Science Journal.

The researchers said Stars and planets share the same solar system from the same gas group. This means that both stars are made up of the same minerals, for example the Earth orbiting the Sun with a low carbon-to-oxygen ratio. So the world will also have low carbon levels. Resulting in a very small amount of diamonds However, the world may only have around 0.001 percent of diamonds.

But exoplanets orbiting stars with a higher carbon-to-oxygen ratio than the sun. Tends to be rich in carbon The researchers suggested that those planets could convert carbon into diamonds and silicates if they had water. This could result in planets having enormous amounts of diamonds.

In 2012, scientists announced that They have discovered planets outside the solar system that are twice the size of Earth. It is believed that most of the planet's area is diamond. Astronomers believe This rocky planet, 55 Cancrie, may be covered with more graphite and diamonds than water and granite.

In the new study The scientists conducted lab tests to support their research. By creating conditions within the planets outside the solar system, the carbon-rich universe And conducted experiments using heat and air pressure
The researchers took samples of silicon carbide, a chemical mixture of silicon and carbon, and put it in water. The reaction between silicon carbide and water was then measured using a laser to generate high heat. X-ray technology was later used to measure the reaction that occurs when a silicon carbide sample is heated to high pressure.

The researchers found that high levels of heat and air pressure caused silicon carbide to react with water. And become diamonds and silica.

However, although this study provides new evidence that some extrasolar planets may contain highly valuable substances. But it does not suggest that the planets are conducive to life. Because these carbon-rich planets often have no conditions that can support any living thing.

The researchers said The internal surface of such planets is so hard that geological motion is impossible The lack of geological activity may prevent the planet from forming the atmosphere. The atmosphere is very important for living things because it is what creates air and water.

Harrison Allen-Sutter said the new telescope from NASA is helping scientists better observe and learn more about exoplanets than ever before. And astronomers have already found more than 4,000 planets outside the solar system and that the more they learn. They will be able to interpret new information in order to better understand the world outside our own solar system.
