An inner sphere of iron and nickel 650 km in diameter in the inner core of the Earth
A new discovery in the internal structure of the Earth has been made by researchers at the Australian National University, who have published their findings in the journal Nature Communications.
Research has shown the existence of an inner sphere of iron and nickel 650 km in diameter in the inner core of the Earth. This discovery represents a major milestone in the development of the understanding of the planet’s magnetic field, which was crucial to the existence of life as we know it.
“The inner core is like a time capsule that allows us to see the history and evolution of the Earth’s magnetic field,” said Juan Esteban Hernández Quintero, head of the UNAM Geophysical Institute’s Magnetic Service, who commented on the discovery. The Earth’s magnetic field is what protects us from the sun’s rays and is essential for life on our planet.
In addition, the inner core affects the Earth’s gravitational field, which represents our planet’s forces. Although we know that the Earth has four layers (crust, mantle, outer core and inner core), the existence of this new core, called the “inner core” by physicists, was revealed due to the study of seismic waves passing through the Earth.
Research has been done by placing detectors around the world to find out how seismic waves move in the most intense tremors that run through the entire structure of the planet. According to the researchers, the inner sphere of iron and nickel is more solid than the outer core and measures about 1,200 km in radius.
Evolution of the solar system and changes in the speed of rotation and translation of the planets
4.5 billion years ago, the universe of our solar system arose, when cosmic dust coalesced by gravity to create the Sun and the orbiting planets. Since then the planet has evolved, changing its speed in rotation and translation as it has cooled.
As the academic world explains, at the boundary between the outer core and the mantle, nearly 10% of the Earth’s magnetic energy is generated. In addition, the researcher added that the planets once had different characteristics due to the distribution of the inner core of the Earth, which caused changes in the length of days and in the layer of the planet.
As the Earth cools, its internal structure evolves and crystallizes. Today the Earth is a unique planet in its structure and properties, as it has an incredible biodiversity and millions of living people.
Inability to dig deep enough to reach the center of the Earth due to extremely hot temperatures
Despite Jules Verne’s popular novel “Journey to the Center of the Earth”, humanity has not yet managed to dig deep enough to reach the center of our planet. Even the Russians tried to do it at one point, but they only managed to dig 10 km from the outer layer, which is 50 km long. Although the technology has advanced significantly, we cannot reach a greater height because of the extreme temperatures that you will find.
Juan Esteban Hernández Quintero Juan Esteban Hernández Quintero, according to the head of the UNAM Geophysical Institute’s Magnetic Service, if we could dig down to about one-sixth of the Earth’s radius, the temperature would exceed 2,000 degrees Celsius and rise to 6,500 degrees in the center. . This meant that any craft that tried to dig that deep would simply blow up.
