Scary sound from outer space. NASA has shown what a black hole sounds like

NASA has released an audio file that allows you to “hear” a black hole. The 34-second recording is really scary. He proves that there are sounds in space as well, and some of them can make you creep.

NASA released a video on social media that shows the sound of a black hole at the center of the massive Perseus galaxy cluster, also known as Abell 426. The cluster is located in the constellation Perseus, 230 million light-years from Earth. Experts became interested in it about 20 years ago after detecting sound waves around its supermassive black hole.

NASA reminded what a black hole sounds like

The video presenting the terrifying, cosmic sound first saw the light of day in May, but NASA decided to recall it again. His description highlights the common misconception that there is no sound in space. As the US space agency explains, it results “from the fact that most of the space is a vacuum that does not allow sound waves to travel. The galaxy cluster has so much gas that we have caught the actual sound. Here it is amplified and mixed with other data to hear black hole “. You can watch the video below and judge for yourself what it reminds us of.

Before the publication of the recording, NASA had to prepare it specially through the so-called “sonification”. This can be explained as translating astronomical data into sound. If the astronomers hadn’t, the sound black hole it would sound completely different because, according to NASA, it is too low to be heard by humans. ABC News explained that the recorded signals were re-synthesized by scaling 57 and 58 octaves above their true height. That is, what we are hearing is actually “144 quadrillion and 288 quadrillion times higher than the original signal frequencies.”

The sounds of the black hole at the center of the massive Perseus galaxy cluster are not the only “sonifications” NASA has released so far. Thanks to the American space agency, we could also “hear” the sounds of the Sun, Jupiter and Saturn. They make it possible to better understand the specifics of the cosmos, and at the same time draw attention to its complexity and the need for further research.
