In this century, an endless series of scientificdiscoveries to surprise the public with something unbelievable is quite difficult. Nevertheless, the Italian scientist from the laboratory of the National del Gran Sasso, the world's largest underground research center, managed to do this. Here we study the structure of our planet and recently, using the Borexino neutrino detector, which is located 1400 meters below the surface of the earth, “ghost particles” from the earth's crust have been discovered. The work was published in the journal Physical Review D.
What are “ghost particles?”
The results of the study for the first time givean idea of the processes in the bowels of our planet, about which until now nothing was known. Mysterious particles known as geoneutrinos are almost impossible to detect because they rarely interact with matter. These particles are formed in the process of radioactive decay in the bowels of the Earth and almost every second at least a million of these “ghost particles” penetrate literally every square centimeter of the surface.

The Borexino detector is one of the few ina world of detectors that can catch a geoneutrino. Scientists have been working with him since 2007, and in 2019, after changing the analysis method, specialists were able to record twice as many events as in the entire previous period. So, it was found that 53 new activities are taking place underground. In this case, the discovery of ghostly particles that make our planet glow, can tell scientists a lot more about other mysterious processes.
Where does the heat inside the earth come from?
According to The Independent, researchersIt is believed that these radioactive processes are responsible for volcanic eruptions and earthquakes, which significantly affect our lives. Moreover, the magnetic field, the movement of tectonic plates and the mantle of the Earth make the Earth truly unique in comparison with other celestial bodies of the solar system. Scientists are trying to answer the question of where the Earth’s internal heat comes from over the course of two decades. And thanks to the discovery of the Heineutrino, the hypothesis that there is no radioactivity in the depths of the planet in the mantle can be refuted with a probability of 99%.

In the future, scientists intend with a higherto study the geoneutrino mantle of the Earth with accuracy. This opportunity will be provided to researchers by the new JUNO project (Jiangmen Underground Neutrino Observatory) - a modern detector whose dimensions are 70 times larger than the dimensions of the Borexino detector. Researchers plan to locate JUNO at a distance of about 52 km from the reactors of the Yangjiang and Taishan nuclear power plants in China.
