NASA releases recording of black hole 'screaming'

The black hole at the center of the Perseus sounding galaxy cluster created ripples in the hot gas of the molecular cloud around it, thereby creating the sound waves collected by the Chandra X-ray Observatory, according to SciTech Daily.

Specifically, the creepy music created by this black hole includes notes in the pitch and inaudible to humans - 57-58 octaves away from the middle C note (C4, C 4th C key from left to right). on the piano keyboard).

To celebrate 'Black Hole Week' 2022, scientists from NASA (US Aeronautics and Space Administration) decided to convert the music to a pitch within the range of human hearing, using data from the Chandra X-ray Observatory.

To make music, sound waves are extracted in radial directions (outwards from the center), then raised to very high tones. The result is a rather creepy recording, like the roar of a beast.

If a black hole erupts in space and no one is around to observe it, does it make a sound?

Not to worry; the @ChandraXray Observatory is here with new #BlackHoleWeek sonifications from galaxy clusters far, far away.

When observing the sky with the X-ray band, the galaxy cluster is the brightest because it always emits intense radio emissions. It is known as the 'singing galaxy cluster'. In 2003, a team of astronomers led by Dr Andrew Fabian at the University of Cambridge discovered one of the deepest nodules ever found after 53 hours of observations by the same Chandra X-ray Observatory.

A similar phenomenon has also been observed with the not-so-distant galaxy cluster, where the singing is produced by an even larger supermassive black hole in the galaxy Messier 87 (also known as M87).
