Have you tired to listen to the latest hits on the radio? NASA has decided to publish a less common audio recording . It is the sound of our planet.
If satellite images have already managed to give us a beautiful view of Earth from almost any angle, in terms of audio content, we have not yet had the chance to experience as how our planet sounds from space. NASA has just released an audio recording of a phenomenon called “choir”.
This choir is composed of radio signals caused by plasma waves found in our planet’s radiation belts. The sounds were captured by a series of space probes carrying out this mission over a period of two years including earth’s belts.
“This is how the radiation belts can be heard to the human ear if we had radio antennas instead of our ears, “said Craig Kletzing at the University of Iowa, trying to explain the phenomenon. The team behind these missions is especially proud of the high quality recording. Unlike other attempts in the past, now it is close to an audio CD quality.
The next stage of this project, the effort is to generate an audio recording in stereo sound. That content should sound better, and have great scientific value.
