Hear a recording of a supermassive black hole in this NASA clip

NASA has released a stunning piece of audio that reveals the eerie sound of a supermassive black hole 250 million light-years away.

NASA has released a stunning piece of audio that reveals the eerie sound of a supermassive black hole 250 million light-years away.

The massive galaxy cluster Perseus, or Abell 426, is at the center. It is the host of a giant black hole. Now, after being processed by scientists, the sound waves from this super black hole have been transferred to 57 and 58 octaves to be audible to the human ear. Thus, the result sounds something like the terrifying howl of an angry creature.

This is the first sound extracted from a black hole and was published by NASA in May based on data from the past decades. Although we cannot hear sound waves in space, it does not mean that there is no sound. In 2003, astronomers were surprised to discover that sound waves are emitted from the abundant gas surrounding the black hole of the Bursaush galaxy cluster. They are less than human hearing, let's hear, but the new process of sound creation (Sonification) has not only moved this slight sound to high octaves, but also added notes to it and made it possible to have a proper understanding of the real sound of the black hole. .

The lowest cosmic note identified in 2003, in musicology, is a B-flat note, which is more than 57 octaves below the Middle C note. ) It is appropriate to. In this step, from the frequency point of view, the duration of the passage of sound from a point is 10 million years. Meanwhile, for the lowest sound that can be detected by humans, this criterion takes only one twentieth of a second!

In data processing, sound waves have been extracted radially and towards the outside of the supermassive black hole and rotated around it. They are emitted in steps of 144 quadrillion (144 thousand trillion) and 288 quadrillion times the frequency of the original sound waves, so we can hear the sounds in all directions of the black hole.

The result is like many other waves recorded from space and transposed to audible audio frequencies. But these sounds are not just a scientific curiosity. The gas and dilute plasma that move between the galaxies of the galaxy clusters, i.e. in the intracluster environment, are denser and much hotter than the environment outside the cluster.

In fact, the passage of sound from the intergalactic environment and the transfer of energy to the plasma causes It gets hotter, and since temperature is effective in the process of star formation, sound waves can play an essential role in the evolution of galaxy clusters in the long term. to detect sound waves. Because the environment inside the cluster, due to being heated by sound, shines brightly in the X-ray spectrum, and thus X-ray observatories like Chandra can not only detect the existence of sound waves, but by identifying their changes, they can also make them sound.

Scientists have also performed the sonication process for another famous megamass black hole. *M87 was the first black hole to be directly imaged in an extensive effort with the Event Horizon Telescope, and was also observed by the Chandra X-ray telescope, the Hubble telescope for visible light, and the Atacama Large Millimeter/Submillimeter Array for radio wavelengths.

The data revealed a massive burst of material that From the supermassive black hole, they were ejected into outer space at speeds apparently faster than the speed of light (which of course is just an interesting illusion!), and now this event has been recorded. They did not come from the Bursaush cluster, but only electromagnetic rays in different frequencies. Meanwhile, the radio data with the lowest frequencies have the least step in the process of sonification and detection of black hole sound. Optical data includes the middle range and the X-ray spectrum has the highest frequencies.

Converting visual data into sound can be a new way to experience cosmic phenomena, and on the one hand, it has scientific value because sometimes, changing a set The data can reveal new hidden details and enable more detailed discoveries about the mysterious and vast universe around us.
