Scientists are puzzled by the "screams of the Earth" during solar storms

In the vacuum of space, sound does not propagate, but there is enough electromagnetic radiation, mainly due to the solar wind. This radiation can be converted into sound - and you can hear how the Earth's magnetosphere reacts to the pressure of solar vortices. It turned out that this process has its own "melody", which changes dramatically during the strikes of a solar storm.

Under normal conditions, with a stable solar wind, its particles are reflected back from the magnetosphere, towards the main flow, which generates magnetoacoustic oscillations. Data collected by the European Space Agency's spacecraft show a calm, monotonous, “chirping” sound predominantly at low frequencies. The Earth's magnetosphere is constantly "singing" in response to changes in the dynamics of the solar wind.

At the moment, records of six major solar storms have been made, and these data amazed scientists. They hoped to record an increase in pressure on the magnetosphere, which would lead to an increase in the frequency of sound, and instead received a complex cacophony of sounds without dominant frequencies. The processes occurring at the boundary of the magnetosphere during solar storms turned out to be much more complicated than we expected.

The new theory says that the particles reflected from the magnetosphere immediately collide with the monstrous pressure of the solar wind, which causes their multiple reflection. Instead of a rhythmic movement, some other process takes place, and we are talking about an energy of such a level that the formation of yet unknown geomagnetic disturbances is possible. They may well pierce the magnetosphere and affect objects even in the planet's troposphere.
