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. "But it's sometimes used to make things seem more 'profound' than they are, like here.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. However, some scientists cautioned that the sonification process was often used to make sounds in space appear more "profound" than they actually are.Ĭhris Lintott, professor of astrophysics at the University of Oxford, wrote on Twitter: "Sonification of data is fun, and can be useful - especially for those who may not be able to see images. belching out incredible songs is a very tantalising thing." Kimberly Arcand, the principal investigator of the Nasa sonification project, told the Washington Post: "The idea that there are these supermassive black holes sprinkled throughout the universe that are. The soundwaves have been likened to Pink Floyd or Hans Zimmer. Here it's amplified, and mixed with other data, to hear a black hole." "A galaxy cluster has so much gas that we've picked up actual sound. 'A galaxy cluster has so much gas we've picked up actual sound'Ī spokesman for Nasa said: "The misconception that there is no sound in space originates because most space is a vacuum, providing no way for sound waves to travel. It was first picked up by Nasa’s Chandra X-ray Observatory in 2003, but researchers have only recently made it audible in a process known as "sonification". "Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency," a spokesperson for Nasa said. The noise is created by pressured waves coming from the black hole which caused ripples in the hot gas, and is 57 octaves below middle C, meaning scientists had to raise the frequency to make it audible to humans. ![]() It can be heard because galaxy clusters contain so much gas that they can allow sound to travel, unlike in vacuums where soundwaves have nothing to bump into. The echoey moans sound similar to whale noises, or a record being played at a slower RPM. ![]() Scientists have released 34 seconds of actual sound coming from the black hole at the centre of the Persus galaxy cluster, some 240 million light years away from Earth, and it is, to say the least, creepy. It is said in space there is no one to hear you scream, but around a galaxy cluster, you might just be heard. ![]()
