There is a song based on magnetic waves generated when the solar wind, the plasma generated by solar flares, hits the Earth’s magnetic field.
Solar flares are explosions that occur on the surface of the sun where charged particles explode. When charged particles emitted by solar flares reach Earth, they collide with the Earth’s magnetic field. As a result of this collision, the Earth’s magnetic field is distracted, causing magnetic field waves.
The disclosure is based on 20-year data collected by a satellite cluster that three-dimensionally investigates the interaction of the Earth’s magnetic environment and solar wind, launched by ESA, from data converted from magnetic waves into audible signals.
Two melodies generated from magnetic field chaos, which can also be sung by the Earth’s magnetic field, are publicly available. One is the conversion of a solar storm, a phenomenon in which a large solar flare occurs, into a song. ESA describes it as an eerie song that recalls the sound effects of science fiction movies rather than a natural phenomenon.
The other is a song from a time when solar flares are mild. The sound pitch is lower and the tune is more monotonous than the sun storm song. When a solar storm occurs, the frequency of the magnetic waves generated when charged particles collide with the Earth’s magnetic field doubles, reflecting that the magnetic waves interfere with each other and become more complex. In addition, a graph showing how magnetic waves become more complex over time as solar storms peak.
The research team that created this song is a research team at the University of Helsinki. It is pointed out that the electromagnetic waves generated by solar storms are far more complex than previously thought. The ESA argues that the study of space weather, such as solar storms, will become important in the future, as solar storms affect Earth and electronic devices.
There are cases where electromagnetic waves from solar storms affect the ground, and in the past, mines floating in the sea were erroneous. Also, most charged particles generated by solar flares are not blocked by the Earth’s magnetic field and collide with the Earth. However, strong charged particles sometimes penetrate the magnetic field. For example, it is the aurora that is generated by charged particles passing through a magnetic field stimulating oxygen and nitrogen atoms in the atmosphere. Related information can be found here .
