The publication of the first photo of Sagittarius A* was the big scientific news of May. And perhaps one of the most important of the year. And even decades! Thanks to many years of work by an international team of scientists, we have succeeded in look in black hole which is located in the center of our galaxy. And if that wasn’t already exciting enough, now we can also hearThanks to ultrasonic processing at the Chandra X-ray Observatoryfrom NASA.
It should be noted that, in fact, we don’t see or hearyes Image taken by the consortium Event Horizon Telescope is the result of computer processing radiation are found around a black hole as it consumes the matter around it. With regard to sonification, this is the second stage of processing, in which a larger volume is assigned to areas with brightness louder and with a higher sound frequency in areas closest to the black hole.
This is not the first time these scientists have conducted an ultrasound examination of an astronomical image. They also did the same with the first black hole ever photographed. M87*and also with supernova remnant Tycho or Perseus cluster. In addition, other researchers have voiced other astronomical phenomena, such as the Martian sunrise, or even biological ones. This is the case of those who have recently turned web patterns into music. Even the first ones became a melody! decimal fractions of pi!
This is the sound of the black hole at the center of the Milky Way.
In this case, scientists proceeded from the image Sagittarius A * black hole posted in the last few days.
The whole photo has been divided as a watch face, so dubbingIt started at twelve o’clock. Then moving clockwise melodyso that the brightest areas are represented Larger volume. In addition, the fastest moving regions closest to the black hole were assigned to higher audio frequencies.
Sonification was performed by scrolling the image clockwise.
On the other hand, as explained in the statement by those responsible for the audio, the result was “processed in a special way so that the listener could listen to the data in 3D stereo sound“. This means that “sounds seem to start straight ahead and then move clockwise to one ear and then to the other as the sound is made.” swept“.
Like the image, all this is more in line with the matter in event horizon than with the black hole itself. Nothing escapes black holes, not even light, so in fact they are all darkness. What is presented is the event horizon, which corresponds to the region from which nothing can escape absorption. This thing revolves around black hole just before it devours this is what we were able to look D listen.
And this is just the beginning. Now there are two, but thanks to methods that are clearly improving, we may soon have many more images of black holes. And why not? Also acoustic performance from this.
