NASA released a series of audio clips from space on April 17th. This is the audible conversion of data collected by the US Space Agency’s THEMIS (History of Major Events and Interactions During Storms) mission. This mission, launched in 2007, consists of five satellites moving through Earth’s magnetosphere, a magnetic bubble that surrounds our planet and protects us from harmful solar radiation.
The sounds come from plasma waves hitting the Earth’s magnetic field lines and Make our world shake. These waves are emitted by the sun, which is constantly sending plasma, or ionized gas, and other high-energy particles into space. These particles can take the form of slow solar winds or fast bursts during solar storms.
The soundtracks are scary. We hear hissing, crackling and growling at high frequency. These sounds are the result of the transformation of the “ultra-frequency” radio waves that are emitted by the changes or vibrations of the plasma shield when they collide with the plasma waves.
these sounds It is not perceived by the human ear, but can be made audible through a process called “revision”. This is to convert numeric data to analog audio signals. This process is used within the framework of the HARP (Heliophysics Incorporated: Resonance in Plasma) project, launched by NASA.
Project HARP aims to give citizen scientists the ability to listen to the sounds of space and Discovering surprising or unusual patterns. These patterns can reveal important information about Earth’s magnetosphere and its interaction with the sun.
Researchers say that by converting data into sound, people can more easily Detect discrepancies or anomalies in charts. They hope HARP will contribute to a better understanding of the physical phenomena that occur in space.
