The majority of space is a vacuum, so sound waves cannot travel there, which is where the myth that there is no sound in space comes from. Let’s see NASA captured the Sound Of A Black Hole.
What happened in the black hole?
The adage “no one can hear you scream in space” refers to the fact that sound waves cannot pass through the vacuum that fills the majority of the universe. According to NASA, however, space can be extremely noisy under the correct circumstances, such as the heated plasma around the enormous black hole at the centre of the Perseus galaxy cluster.
The organisation recently shared an unsettling audio clip on Twitter that depicts genuine sound waves resonating through the gas and plasma in this 250 million light-years away cluster.
NASA captured the Sound
Unless you’re a colossal black hole, no one can hear you cry in outer space.
On Sunday, NASA shared what the organisation referred to as the sound of a black hole in a listenable format, making this abundantly clear.
And NASA has an answer for the question of how the hell sound travels in the void of space.
You are “hearing” the Perseus galaxy cluster, which was recorded in May for NASA’s Black Hole Week using data from the Chandra X-ray Observatory. 57 octaves below middle C, according to NASA’s explanation at the time, “astronomers determined that pressure waves blasted out by the black hole generated ripples in the heated gas of the cluster that could be translated into a note.”
How the sound like?
It simply sounds like the opening of a really ominous dubstep music to us.
But there are more nicer ways to “sonify” black holes. The black hole at the heart of Galaxy Messier 87, or M87, which is around 54 million light years away, has also been sonified by NASA.
What are the data captured from the Black hole?
Yes, this is the one captured in humanity’s first image of a black hole through the Event Horizon Telescope. The track uses data captured from several telescopes — the Chandra X-ray Observatory, NASA’s Hubble Space Telescope, and the Atacama Large Millimeter Array (ALMA) in Chile — and maps the wavelengths to a different range of audible tones. The result, while very far from actual sound a black hole makes, is something you might enjoy at your next yoga session.
What NASA tweet?
The majority of space is a vacuum, so sound waves cannot travel there, according to the agency, which claimed that there is no sound in space. “There is so much gas in a galaxy cluster that we have detected genuine sound. The sound of a black hole is amplified and combined with other data here.”
The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we’ve picked up actual sound. Here it’s amplified, and mixed with other data, to hear a black hole! pic.twitter.com/RobcZs7F9e

Although the black hole’s audio waves were initially discovered in 2003 in data from NASA’s Chandra X-ray Observatory, they have never before been brought within the audible range of the human ear.
Is it a real sound?
Because it revisits the real sound waves found in data from NASA’s Chandra X-ray Observatory, this sonification differs from others in some respects, according to NASA.
“The sound waves previously recognised by astronomers were extracted and rendered audible for the first time in this new sonification of Perseus.”
What is a black hole?
In fact, this black hole is a real cosmic baritone, with sound waves in their natural environment 57 octaves below the middle C. Scientists increased these earthquakes’ frequencies by quadrillions of times to make them audible to humans.
Because of how eerie it is, it would fit right in on a Halloween playlist. The genre of “space sonification,” however, in which astronomical data of various kinds is transformed into sound waves, is home to many more hallucinogenic earworms.
In light of this, if you’re searching for some further off-Earth jams, take a listen to these authentic recordings from Mars, the music of gravitational waves, and the resonances of planetary systems.
