NASA managed to convert the “light echoes” of a black hole located 7,800 light-years away from Earth in sound. This is how this celestial body is heard.

Is about the “light echoes” of the black hole called V404 Cygni, which are the product of intense bursts of electromagnetic radiation that surround radio, visible light, and X-rays that cannot escape the black holes, converted into sound thanks to a new sonificationas reported by the National Aeronautics and Space Administration (NASA).

To achieve this, use the images of X-ray light echoes around V404 Cygni taken by NASA’s Chandra X-ray Observatory and the Neil Gehrels Swift Observatory. Because astronomers know exactly how fast light travels and have determined a precise distance to this system, they can calculate when these flares occurred. These data, along with other information, help astronomers learn more about dust clouds, including their composition and distances.

Therefore, the sound of “light echoes” from the black hole is obtained by translating Chandra and Swift’s X-ray data into sound.

During the sonification, the cursor moves outward from the center of the image in a circle. As it passes through the light echoes detected in the X-rays (seen as concentric rings in blue by Chandra and red by Swift in the image), there are ticking sounds and changes in volume to indicate detection of lightning. X and the brightness variations.

To differentiate between the data from the two telescopes, the Chandra data is represented with higher frequency tones, while the Swift data is lower.

In addition to the X-rays, the image includes optical data from the Digitized Sky Survey that shows background stars. Each star in optical light activates a musical note. The volume and pitch of the note are determined by the brightness of the star.

The V404 Cygni is a system containing a black hole, with a mass between five and 10 times that of the Sun, which is extracting material from a companion star in orbit around it. The material is funneled into a disk surrounding the stellar-mass black hole.
