Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. Now you can listen to it.If a black hole devours a planet and no one is around to hear it, does it still make a sound? Physicists and astronomers have been trying to map astronomical data through sound for decades—and now we can finally listen to a black hole scream into the void.
In this new sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted in radial directions, that is, outwards from the center. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch—or in other words, they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency.
The universe is rife with the hum of celestial melodies—but it’s only relatively recently that humans have developed the technology to be able to hear them. A team of scientists at NASA’s Chandra X-ray Observatory were able to extract and make audible previously identified sound waves from a nearly 20-year-old image of the Perseus galaxy cluster—a collection so full of galaxies, it’s assumed to be one of the most massive objects in the universe.
“This sort of bespoke method is really about extrapolating something new out of this archival information,” says, the visualization scientist for NASA’s Chandra X-ray Observatory who led the research. Translating scientific data into acoustic signals has also become vastly easier in the past few years. For example, scientists can create parameters for all kinds of numerical data by assigning those values to higher or lower pitches, or vice versa, to turn them into musical notes.
These short sonifications typically take a few hours to create, but with the right data, can be completed using sound engineering software and other publicly available computer programs, like
It sounds exactly how I imagined. Not disappointed 😊
Kewl !
Damn the beats are fire son 🔥🔥🔥
I`ve already listened 🤣
Good read! Black holes are fascinating. I watched a docu about them -- way beyond my scope of understanding. But! I learned that they are chaotic and that inside the Event Horizon, space is being pulled into the center --- faster than the speed of light.
