NASA recently unveiled a new recording of the sounds of space. This time, the agency showed what a distant black hole sounds like. According to Science Alert, it is located at a distance of more than 200 million light-years from Earth in the Perseus cluster of galaxies.
This cluster consists of several galaxies, the width of which is 11 million light years. They are surrounded by hot gas. It is these gas clouds that cause the sound vibrations that each of us can now hear.
A few years ago, scientists discovered that the Perseus cluster of galaxies emits waves that pulsate in hot gas. It surrounds a cluster of galaxies, and the waves can be converted into sound.
It is worth noting that on Earth, sounds occur differently. So, they appear due to the vibration of molecules and atoms in the air. But since space is a vacuum where there is no air, vibrations cannot create noise. But this does not mean at all that there are no vibrations.
The Perseus black hole is very close to the cluster’s gas clouds. This creates vibrations of sound waves in the form of gas ripples. And in 2003, astronomers at NASA’s X-ray Observatory converted the ripples into sounds. But they were below the level that the human ear can pick up.
Therefore, NASA scientists increased the sound data by 57 and 58 octaves. This allowed people to hear the massive black hole at the center of the Perseus galaxy cluster.
