In Science and Space: What does a black hole sound like? The audio NASA posted on her Twitter account is “creepy” and “out-of-this-worldly beautiful,” according to people listening to the clip.

The 34-second clip set social his media ablaze, leaving many people stunned that anything could escape a black hole, let alone an eerie throaty moan. But the idea that there is no sound in space is actually a “common misconception,” the agency said. While most of the universe is a vacuum with no medium for sound waves to propagate, galaxy clusters “have abundant gas that envelops hundreds or thousands of galaxies and represent a medium for the propagation of sound waves.” explained.

The US space agency has tweeted what it calls a remixed sonification of a black hole at the center of a galaxy cluster called Perseus, about 240 million light-years away from Earth. Sound waves that were spotted there almost 20 years ago were “extracted and audible” for the first time this year, according to NASA.

Dubbed “Black Hole Remix” by NASA, the clip was first released by him in early May to coincide with NASA’s Black Hole Week. .

“It was a beautiful representation of what was in my mind,” Chandra’s visualization scientist and head of emerging technologies told The Post. But it was also a “watershed moment” for the entire Sonification program, as it “really captured people’s imaginations.”

It also indicates future research areas. “The idea that there are these supermassive black holes scattered throughout the universe and emitting incredible songs is a very compelling one,” Arcand added. Experts warn that the NASA remix sounds very different from what you’d hear if you were somehow standing next to a black hole. The human ear “wouldn’t be sensitive enough to pick up these sound waves,” Michael Smith, an astronomy professor at the University of Kent in England, told The Washington Post. “But they were there, the right kind of frequencies, and if you boosted them, you could hear them,” Smith said. He compared it to radio – ” If you turn up the volume, it will get louder and you will hear it.”

Arcand said the idea took shape during the coronavirus pandemic. She worked on converting her X-ray light into images captured by Chandra’s orbiting telescope. This included creating a printable 3D model of her, making the data easily accessible to those who are blind or blind. Maintaining this program remotely became difficult when the pandemic hit. So she decided to try something new with her other colleagues. Soundification, the process of converting astronomical data into sound. This team of blind professionals inspired Arcand to “think differently” about the value of transforming complex data sets into sound.

Looking at her 2003 data from the Perseus cluster, she and her colleagues determined the properties of pressure waves, deduced the sounds they make, and increased their frequencies. The decision to publish a “re-sonification” of nearly 20-year-old data marks the institution’s effort to use social media to communicate complex scientific findings to its millions of followers in plain English. is part of Through its partnership with Twitter, NASA said, “While its fans enjoy seeing great pictures of space and behind-the-scenes glimpses of missions, there was a group of people who wanted to know what the universe sounds like.” I found press release.

Still, he said, “These galaxy clusters are so far away that we have to make a lot of assumptions to make them sound like we were there. Arcand said she understands criticism from several angles that sound risks simplifying a complex process – especially because the combination of pressure, heat and gas creates sound waves in galaxy clusters. Perseus is specific to this environment. But the value of respect, she says, is that it makes her “question things in different ways.”

“Data sonication is fun and useful, especially for people who can’t see images, but it can also be used, like here, to make things look ‘deeper’ than they really are,” Lindot said. added.
But Smith, a professor at the University of Kent, said: Chris Lindot, an astrophysics professor at the University of Oxford, said on Twitter on Tuesday that the clip was confusing because the audio gave the impression that it was “something you’d hear if you were there.” There was a recording device that transmitted sound from the galaxy cluster directly to Earth.
