NASA broadcasts the disturbing sounds caused by plasma waves striking the Earth's magnetic field

If space produced a symphony, what would its sound be? As the site states Technical sciencesOn April 19, the Earth was surrounded by a particularly rich magnetic environment of very low waves. Although these waves are inaudible to our ears, they represent the turbulent and tumultuous relationship between the Sun and the blue planet.

However, a new citizen science project, called “Audified Heliophysics: Resonance in Plasma” (HARP) funded by NASA, has made it possible to convert these plasma waves, which strike the Earth’s magnetic field, into whispers that humans can hear. Sounds that seem relatively unpleasant to the ear, which it perceives as creaks, whistles or streams.

The distance between the sun and the earth is not completely empty. On the contrary, it contains plasma charged particles, states the same site dedicated to science and technology news. Said plasma is emitted directly from the sun, in the form of sporadic solar flares and solar winds. Once the solar plasma hits the Earth, the latter causes the magnetic field lines to vibrate, as does the Earth’s plasma. In the second step, ultralow waves are produced.

Participants in this NASA-funded project are invited to listen to sounds from space through an interactive tool to help scientists discover new information about the relationship between the Earth and the Sun. Thus, they are asked to listen to these waves and then identify properties they find interesting. Michael Hartinger, a heliophysicist at Colorado Space Institute and researcher on this project, said he was pleased that “citizen scientists” had the opportunity to participate in the research through acoustic analysis.
