On March 18th, Beijing time, according to foreign media reports, at present, researchers directly measure how energy is converted from chaotic electromagnetic fields in space into solar wind. Previously, scientists believed that the "Landau damping" process was responsible for providing energy to the electrons in the solar wind and increasing the temperature of interstellar space. Observation data from NASA's artificial satellites have measured this process and confirmed this conclusion. Scientists at Queen Mary University of London (QMUL) in the United Kingdom said this discovery will help us better understand how the solar wind heats through space. Previously, scientists believed that the "Landau damping" process was responsible for providing energy to the electrons in the solar wind and increasing the temperature of interstellar space. Observation data from NASA's artificial satellites have measured this process and confirmed this conclusion. The solar wind is a stream of charged particles from the sun, or plasma, which fills our entire solar system. Understanding these particles in the solar wind is crucial for studying interstellar matter, the radiation that exists in space, and the plasma disks around black holes. The study's lead author, Dr. Christopher Chen, Queen Mary University of London, said: "Plasma is currently the most abundant form of visible matter in the universe, usually a highly turbulent, apparently chaotic state called turbulence. " This turbulence transfers energy to the plasma particles, causing these particles to heat and carry energy, making turbulence and related heating phenomena very common in the universe. The research team used high-resolution measurement data from NASA's magnetospheric multiscale detector (MMS) and a newly developed data analysis technique. The MMS detector is located in the solar wind and measures the magnetic field and particle flow. "Landau damping" is a phenomenon responsible for transmitting electromagnetic wave energy to charged particles in the solar wind plasma. This process was originally discovered by Nobel Prize winner and physicist Lev Landau. At that time, Landau found that electromagnetic waves passed through plasma (ionized gas composed of ions and electrons), and these charged particles had the same speed as electromagnetic waves. The energy from the electromagnetic wave is then absorbed by the charged particles of the solar wind, thereby reducing the electromagnetic wave's own energy during the "Landau damping" process. The "Landau damping" process has been measured before, but it is not yet known whether it is suitable for complex plasmas in space. Throughout the universe, matter is in an energetic plasma state, and its high-temperature environment far exceeds previous expectations. For example: the temperature of the corona is hundreds of times the temperature of the sun's surface, and scientists are still trying to reveal the mystery. Dr. Christopher said: "In this study, for the first time, we directly measured the phenomenon of turbulent heating in the process of naturally occurring astrophysics plasma. At the same time, we also confirmed a new analysis technology, which is a kind of detection technology Energy plasma tools can also be used for subsequent research on different characteristics of plasma behavior. " In addition to this, the research also laid the foundation for future missions to survey other areas of the solar system. For example: NASA's "Parker" solar probe began to explore the corona and plasma environment near the sun for the first time. Currently, this latest research report is published in the journal Nature Communications.
