A kind of radar scan of oursupermassive. With changes of which represent the different observed by the EHT around the of Sgr A*. the closer to the black hole, and which therefore moves faster, is translated by higher sound. And with sonication in 3D stereo sound, sounds appear to move as the radar scan, in the from ear to ear.

The same researchers also worked on the sonification of the region surrounding theat the center of the Milky Way. On the image, we discover the area as seen in (orange and purple) and in (blue). Once again, the luminosity of objects is translated into volume. The vertical positions on the image are transcribed by musical pitches. X-rays are played by a soft synthesizer. Low notes and plucked sounds feature infrared.
