What is the B-flat of a black hole?
In musical terminology, this B flat is 1-1/2 steps from middle C. The Perseus cluster black hole’s B-flat, by contrast, is 57 octaves below middle C or one million, billion times lower than the lowest sound audible to the human ear!

Can X-rays from a black hole be converted into sound?
Meanwhile, Dr. Kara has been working with education and music experts to convert the X-ray reflections into audible sound. In some simulations of this process, she said, the flashes go all the way around the black hole, generating a telltale shift in their wavelengths before being reflected.
What is ‘black hole week?
All this is an outgrowth of “Black Hole Week,” an annual NASA social media extravaganza, May 2-6. As it happens this week provides a prelude to big news on May 12, when researchers with the Event Horizon Telescope, which in 2019 produced the first image of a black hole, are to announce their latest results.
What is inside a black hole?
A black hole has a gravitational pull that is so intense that nothing, not even light, can escape it once inside a certain region, called the event horizon.

Can you hear the sound of a black hole?
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.
What are the audio files and visualizations NASA released about black holes?
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."
What is sonification of the black hole?
This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year.

Can we hear sound from a black hole?
Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C.
Where is the black hole in the Messier 87 galaxy?
The space agency also released a new sonification of a black hole that became famous in 2019. That black hole sits at the center of the Messier 87 galaxy, about 55 million light years from Earth. It gained fame when astronomers announced they had successfully produced the first image of a black hole.
