The United States Space Agency (NASA) has published unreleased audio from black hole sound in the Perseus cluster of galaxies, located 250 million light-years from Earth. According to scientists, the capture is unlike anything done before.
This feat occurred in a process called “dubbing”, which converts in-depth astronomical data into sound elements. To do this, scientists used computers and advanced software to “translate” information that is not audible to humans into sound waves. Thus, the noise of a black hole can be picked up and heard from us.
“In a way, this ultrasonic processing is unlike anything that has been done before because it revisits the actual sound waves found in the data from the Chandra X-ray Observatory. [telescópio espacial lançado pela agência em 1999]”, NASA said in a statement.

The projects focus on space travel and advanced concepts in computing and robotics.
In 2003, it was found that the pressure waves from the orifice cause ripples that can be converted to an audio frequency that is not audible to the human ear, about 57 octaves below middle C. As explained astronomythe signals were “boosted” and heard 144 quadrillion and 288 quadrillion times higher than their original frequency.
In addition, NASA also announced a new voiceover for yet another black hole, this time from space. galaxy m87. It was recently revealed that this black hole was imaged by the Event Horizon Telescope (EHT) project in 2019. “Sonification scans the image of three layers from left to right, with each wavelength corresponding to a different range of audible tones,” explains the researcher. space agency.

Sound in space?
If space is basically a vacuum, how can we hear the sound of a black hole?
In fact, according to the laws of physics, sound is a mechanical wave and requires a medium to propagate. “The popular misconception that there is no sound in space stems from the fact that most of space is essentially a vacuum that does not allow sound waves to propagate,” NASA explains in its publication.
The concentration of gases in clusters of galaxies allows you to capture sound waves
However, as the researchers explain, a cluster of galaxies (such as Perseus) contains a large amount of gas surrounding hundreds or even thousands of galaxies, which allows the agency’s instruments to pick up sound waves.
