Detects molecules that help measure activity at the Sun's core

An Italian laboratory located at a depth of 1.4 km in the heart of the Apennine has discovered molecules from the Sun that can help measure activity at the planet's core.

The information was published in the British Natural Science magazine on August 27.

The laboratory has recorded low-energy neutrons (called pp neutrons , molecules to measure the "living" signs of the Sun), emitted during the melting of hydrogen particles of protons and mechanisms. in which the Sun core generates energy.

By comparing the two different energies that the Sun emits are neutrons and surface light, scientists have obtained information about the activity of the Sun over a period of over 100,000 years.

Researchers Andrea Pocar of the University of Massachuserrs said that with neutrons recorded, scientists not only see clearly the "face" that the core, or "the soul" of the Sun.

The protein emits from the Sun at nearly the speed of light. About 65 billion neutron particles touch a square centimeter of the Earth's surface every second. These molecules graze very light matter without leaving a trace but it is difficult to identify because of its signs very much like molecules emitted from natural stone radiation.

Italy's laboratory is located deep underground to protect detectors from other radiation sources, including Borexino equipment, a steel ball that is "smooth" with 1,000 tons of ultra-clean water, 300 tons inside. Pure hydrocarbon solution similar to benzene. The surface of this sphere glows when facing neutrons.

The neutrons continuously shot out of the Sun and landed after only 8 minutes. Meanwhile, it takes from 100,000 to 200,000 years for the energy remaining after the melting process to turn into photons, light molecules passing from the Sun to the ground. The comparison of the number of neutrons and photons helps physicists determine whether the Sun's energy changes during this time.

According to the French National Center for Scientific Research (CNRS), the organization that participated in the study, the unique experiment results show that the Sun's activity has remained unchanged for over 100,000 years.
