Last Wednesday (4), the United States National Aeronautics and Space Administration (NASA) published sound with a noise produced by black hole. Scientists used astronomical data from the black hole and computer software to create human-audible sounds – in other words, they translated astronomical data into sound.

The black hole at the center of the hero galaxy cluster is often associated with sound by scientists. In 2003, it was discovered that pressure waves from the hole cause ripples about 57 octaves below middle C, which can be translated into a sound frequency not perceived by the human ear.

Thus, the data was resynthesized and raised 57 and 58 octaves above the true pitch so that the sound reaches human hearing. According to NASA, this means that the sound is approximately 144 quadrillion and 288 quadrillion times louder than the original frequency, respectively.

Although sound does not propagate in vacuum, there is a large amount of gas surrounding a galaxy cluster, providing a means to propagate sound waves. In other words, it is a myth that there is no sound in space – just find the right place and you can find “space symphonies”.

The scientists also created the sound of a black hole in the supergiant elliptical galaxy Messier 87 (M87), which has been studied by researchers for years. Sonifications were performed by scientist Kimberly Arcand, astrophysicist Matt Russo, and musician Andrew Santaguida with data from the Chandra X-ray Observatory.

“The brightest region on the left of the image is where the black hole is, and the structure in the upper right is a jet produced by it. Sonification sweeps the image in three layers from left to right, each wavelength having a different map of the audible tonal range,” NASA explained in a statement.

“Radio waves are mapped to the lowest tones, optical data to the midtones, and the X-rays detected by Chandra. [telescópio espacial que observa raios-x] for higher tones, the brightest part of the image corresponds to the highest part of sonification.”
