![]() The new "sonification" - which was released as part of NASA's Black Hole Week this year - is essentially a translation of astronomical data, scaled up 57 or 58 octaves above their true pitch so it can be heard by humans. Recorded by the agency's Chandra X-ray Observatory, the recording is of pressure waves sent out by the black hole within the Perseus galaxy cluster, which causes ripples in the cluster's hot gas. M87 gained celebrity status in science in 2019 as it was the first black hole ever to be directly imaged in a colossal effort by the Event Horizon Telescope collaboration.NASA has released an audio recording of a black hole. The black hole in Messier 87, or M87, has been studied by scientists for decades. NASA has also released another sonification of a famous black hole. Blue and purple areas show X-ray data captured by Chandra. The radar-like scan around the image allows you to hear waves emitted in different directions. Astronomers resynthesised the audio and scaled them upwards around 58 octaves so that it is audible to humans. The sonification is unlike any other, as it revisits the actual sound waves discovered in data from NASA’s Chandra X-ray Observatory - a sophisticated space telescope.

The new sonification - that is, the translation of astronomical data into sound - was released for NASA’s Black Hole Week on May 4, 2022. The note was, however, not audible for human ears as it was some 57 octaves below middle C. These ripples in the cluster’s hot gas could be translated into a note. NASA astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas. The black hole in the Perseus galaxy cluster has been associated with sound since 2003. “The sound waves were extracted outward from the centre,” The audio description said. These were first made audible three months ago when NASA uploaded the video on YouTube. However, a galaxy cluster 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, said NASA.Īstronomers had earlier identified and extracted the sound waves from the black hole. It originates from the fact that most space is essentially a vacuum, providing no medium for sound waves to propagate through. It is a popular misconception that there is no sound in space.

Here it's amplified, and mixed with other data, to hear a black hole! /RobcZs7F9e A galaxy cluster has so much gas that we've picked up actual sound. The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. ![]() ![]() We represent all of NASA’s missions looking for - and finding - new worlds,” stated the team’s Twitter handle. “We are the NASA team looking for planets and life beyond our solar system. The Twitter handle of NASA Exoplanets tweeted the audio clip with a visual. The clip, shared on microblogging platform Twitter, took many by surprise, with many commenting on the ‘ghostly’ nature of the sound and how audio can be recorded in space. The United States National Aeronautics and Space Administration (NASA) shared a haunting audio clip of a supermassive black hole located 250 million light-years away. ![]()
