nasa black hole sound (perseus galaxy cluster) 

Apart from seeing some celestial wonders they can also be experienced with other senses. Through data sonification, the same digital data that gets translated into images turns into sound.

Scientists previously believed that there is no sound in space, as much of space is essentially a vacuum, providing no medium for sound waves to propagate.

Whereas scientists now say that a galaxy cluster contains abundant gas that surrounds hundreds or thousands of galaxies within itself, providing a medium for sound waves to travel.

New Sonification is the translation of astronomical data into sound. This sonification translates to actual sound waves detected in data from NASA's Chandra X-ray Observatory.

The black hole at the center of the Perseus galaxy cluster, about 250 million light-years from our Earth, has long been associated with sound.

In 2003, astronomers discovered that pressure waves sent out by this black hole cause ripples in the cluster's gas, which can be translated into a note that, however, cannot be heard by humans. But NASA has created a sonification of this sound, which can be heard.

In the Sonification of Perseus, the sound waves previously identified by astronomers were ejected in radial directions (outwards from the centre).

After extraction, the signals were synthesized in the range of human hearing by scaling them to 58 octaves from their actual pitch.

The frequency of the sound waves was recorded to be 57 octaves lower than that of the human ear. However, after raising the sound wave frequency to 144 quadrillion times (1,44,00,00,00,00,00,00,000) higher than the original frequency, the sound of Perseus can be heard.

Video from NASA (Black Hole Sound) shows a radar-like scan that shows how the sound shoots out in different directions when you listen to it. Click Here to listen to the sound of black hole- https://www.youtube.com/watch?v=ioR5np1fmEc&t=34s

What are Galaxy Clusters? Galaxies are the building blocks of the universe that contain a large number of stars. There can be 3-20 galaxies in galaxy groups and their abundant structure is called 'cluster'. There are hundreds of galaxies in a galaxy cluster.

What are Superclusters? Superclusters are 'clusters of clusters'. It can have at least two clusters. The Schaple supercluster was first discovered.

What is Perseus Galaxy Cluster The Perseus Cluster is a group of galaxies in the constellation Perseus. It is one of the most massive objects in the known universe, containing thousands of galaxies, shrouded in a giant cloud of multimillion-degree gas.

What is Messier 87 Messier 87 (M87), is an elliptical galaxy about 55 million light-years away from Earth. At its center is a black hole whose mass is 6.5 billion times that of our companion Sun. The sound of the M87 and its supermassive black has also been recorded.
