When you think of a black hole, most people think of a giant scary mass of energy that sucks the life out of the universe! (think movies like Event Horizon , Interstellar , Star Trek !)
Well, this week NASA’s exoplanets Twitter account released an audio clip of what a black hole some 240 million light years away sounds like, and let’s just say adjectives like eerie, creepy, and chilling really don’t do it justice because it literally sounds like you can hear the souls of stars and planets being sucked out of the universe!
NASA released the audio to clear up the misconception that there is no sound in space because it’s a vacuum and there’s no way for sound waves to travel.
The agency said it picked up the sound from a galaxy cluster that had a lot of gas.
The actual sound is actually too low for humans to hear, so if you were close to the black hole, you wouldn’t actually hear it.
NASA amplified the sound and mixed it with other black other data so we could hear it.
Still, now we know. And we’ve heard it and can’t unhear it.

Is there sound in space? New audio released from NASA provides some insight – and the answer is haunting.
The audio, released on May 4 , is that of a black hole from the center of the Perseus galaxy cluster , a massive space structure that's 11 million light-years across and located about 240 million light-years away from Earth. Astronomers created the audible sound by recording the pressure waves that the black hole sent through the cluster's hot gas. In their original form, those waves cannot be heard by the human ear, so scientists extracted the sound waves and scaled them up by 57 and 58 octaves.
"In some ways, this sonification is unlike any other done before," NASA said in a release. "...[The sound waves] are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency."
When bumped up to human frequencies, the sounds of the black hole are almost akin to the wails of a haunting ghost or the deep ocean calls of a pod of whales.
While this particular sound of space is new, NASA has associated the Perseus galaxy cluster with sound since 2003. Galaxy clusters like Perseus are the largest gravitationally bound objects in the universe containing hundreds of galaxies, massive clouds of hot gas that reach more than 180 million degrees Fahrenheit and the ever-mysterious dark matter. All of that material creates a medium for sound waves to travel.
Along with releasing the sounds of Perseus, NASA scientists have also released a sonification of another famous black hole located in Messier 87, or M87.
Unlike Perseus' black hole, this one has a far higher pitch, and can best be described as ambient music with light chimes. The visualization of the sound that NASA released is just as spectacular, as it contains scans of the black hole taken by the Chandra X-ray Observatory, optical light from Hubble Space Telescope and radio waves from the Atacama Large Millimeter Array in Chile. It also contains an image of where the black hole is located and an image of a jet that M87 has produced.
The audio files and visualizations were released during NASA's Black Hole Week from May 2 to 6. During that time, NASA released various visualizations and information about black holes as part of a "celebration of celestial objects with gravity so intense that even light cannot escape them."

NASA is figuring out how outer space sounds NASA began "sonifying" its famous photos of outer space to help people who are visually impaired enjoy the images. Recently, it recreated the sound of a black hole 240 million light-years away.

A bounty of black holes surround the Sagittarius A supermassive black hole which lies at the center of our Milky Way Galaxy.

A bounty of black holes surround the Sagittarius A supermassive black hole which lies at the center of our Milky Way Galaxy.
For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.
NASA released a 35-second audio clip of the sound earlier this month using electromagnetic data picked from the Perseus Galaxy Cluster, some 240 million light-years away.
Sonification of the black hole at the center of the Perseus Galaxy Cluster.
The data had been sitting around since it was gathered nearly 20 years ago by the Chandra X-Ray Observatory . The decision to turn it into sound came only recently, as part of NASA's effort over the past two years to translate its stunning space photography into something that could be appreciated by the ear.
"I started out the first 10 years of my career really paying attention to only the visual, and just realized that I had done a complete disservice to people who were either not visual learners or for people who are blind or low-vision," NASA visual scientist Kimberly Arcand told NPR in an interview with Weekend Edition .
While the Perseus audio tries to replicate what a black hole actually sounds like, Arcand's other "sonifications" are more or less creative renditions of images. In those imaginative interpretations, each type of material — gaseous cloud or star — gets a different sound; elements near the top of images sound higher in tone; brighter spots are louder.
For more examples of NASA's sonifications, go to the agency's Universe of Sound web page. Or read on to learn more from Arcand about the venture.
On how the black hole audio was made
What we're listening to is essentially a re-sonification, so a data sonification of an actual sound wave in this cluster of galaxies where there is this supermassive black hole at the core that's sort of burping and sending out all of these waves, if you will. And the scientists who originally studied the data were able to find out what the note is. And it was essentially a B-flat about 57 octaves below middle C. So we've taken that sound that the universe was singing and then just brought it back up into the range of human hearing — because we certainly can't hear 57 octaves below middle C.

So, we actually take the data and we extrapolate the information that we need. We really pay attention to the scientific story to make sure that conversion from light into sound is something that will make sense for people, particularly for people who are blind or low vision. So our Milky Way galaxy — that inner region — that is this really sort of energetic area where there's just a whole lot of frenetic activity taking place. But if we're looking at a different galaxy that perhaps is a little bit more calm, a little bit more restive at its core it could sound completely different.

This is like a baby stellar nursery. These tall columns of gas and dust where stars are forming and you're listening to the interplay between the X-ray information and the optical information and it's really trying to give you a bit of the text.
These soundscapes that are being created can really bring a bit of emotion to data that could seem pretty esoteric and abstract otherwise.
