NASA captures sound of a black hole for the first time and it sounds just like you imagined

Ammon News - Science fiction films have been getting it pretty close.

NASA has recorded the sound of a black hole for the first time ever - and it sounds eerie. The amazing feat was achieved as a result of the "echoes", which are space phenomena released in the form of X-rays.

In 2003, NASA’s Chandra X-ray Observatory detected the waves in the Perseus galaxy cluster. Now, they have been converted from data into sound waves for NASA's Black Hole Week 2022, Express.co.uk reports.

NASA said in a statement: "In some ways, this sonification is unlike any other done before because it revisits the actual sound waves discovered in data from NASA's Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through.

"A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel."

In addition to the Perseus galaxy cluster, a new sonification was released of the black hole in Messier 87, or M87. This black hole gained celebrity status in science after an image was released from the Event Horizon Telescope (EHT) project in 2019.

NASA added: "The sound waves were extracted in radial directions, that is, outwards from the centre. The signals were then synthesised into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch.

"Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency."

Black holes are regions of spacetime that are formed when massive stars collapse at the end of their lives and can continue to grow by absorbing and merging with other black holes. This interaction has been observed for decades and scientists use it to identify their presence, as radiation is given off as visible light across space.

Astronomers have previously declared that gravity is so strong inside the cosmic phenomena's boundary that nothing – not even light – can escape from its event horizon. In addition to the supermassive black hole at its core, the Milky Way is believed to contain tens of millions of stellar black holes.
