💥 The idea that there is no sound in space is a popular misconception.

Most of space is a vacuum that sound waves can't move through, but galaxy clusters can release a lot of gas, which envelops the many galaxies inside of them, creating a medium for sound waves to travel through.

In 2003, astronomers found that pressure waves sent out by the black hole at the centre of the Perseus galaxy cluster caused ripples in the cluster's hot gas, which could be translated into a note.

The thing is, the note was too low to be heard by humans, because it is 57 octaves (or about seven piano lengths) below middle C, according to NASA.

To create audio that is audible to humans, scientists do something known as sonification, which is the translation of this astronomical data into sound.
