NASA released a creepy recording from a “screaming” black hole – Information Technology
The monstrous black hole at the center of the singing galaxy cluster Perseus created ripples in the hot gas of the molecular cloud around it, forming the ghostly sound waves that the Chandra X-ray Observatory picked up.
According to SciTech Daily, the spooky music created by this monster black hole creates notes in the pitch and inaudible to humans – 57-58 octaves away from the middle C (C4, C minor). from left to right on the piano keyboard).

To celebrate “Black Hole Week” 2022, NASA scientists decided to convert the track to a pitch within the range of human hearing, using data from the Chandra X-ray Observatory.
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.
