According to SciTech Daily, spooky music do monster black hole This produces notes in pitches that are inaudible to humans – 57-58 octaves away from the middle C (C4, fourth C from left on a piano keyboard).

To celebrate “Black Hole Week” 2022, NASA scientists decided to convert the music to a pitch within the range of human hearing, using data from the Observatory X ray Chandra.
To make music, the sound waves are extracted in radial directions, ie outward from the center, then raise the tone very high. The result is a rather creepy recording, more like the roar of a beast.

When observing the sky with the X-ray band, the galaxy cluster is the brightest because it always emits intense radio emissions.
It is also known as the “singing galaxy cluster”. In 2003, a team of astronomers led by Dr Andrew Fabian at the University of Cambridge (UK) discovered one of the deepest nodules ever discovered, after 53 hours of observations also by the X-ray Observatory. X Chandra.
The same phenomenon has also been observed with the nearby Virgo cluster, with singing produced by an even larger supermassive black hole in the galaxy Messier 87.
