Like nothing else, “NASA” reveals the sound of a black hole for the first time
The US space agency “NASA” published a video clip that reveals for the first time the sounds emanating from a black hole in the center of the Perseus group of galaxies, which are more than 200 million light-years away from Earth.
"In some ways, this sound is unlike anything else that has been made before, as it reconsiders the actual sound waves detected in data from our Chandra X-ray Observatory," NASA said in a statement.
And in 2003, astronomers discovered that pressure waves sent by the black hole at the center of Perseus produced ripples in the surrounding hot gas, which can be translated into a sound note.
However, this was not audible to the human ear, but NASA translated this astronomical data into sound using a process called sonication.
“NASA” pointed out a common misconception that “there is no sound in space, which arises from the fact that most of space is essentially a vacuum, and provides no means for sound waves to propagate through it.”
She added, "It turns out that the Perseus cluster of galaxies contains abundant amounts of gas that encase hundreds or even thousands of galaxies inside, providing an ideal medium for sound waves, allowing us to hear what this part of space looks like."
She explained that the new sonication process included the extraction of sound waves in radial directions, i.e. outward from the center, after which the signals in the human hearing range were recombined by raising them up by 57 and 58 octaves above the real sound layer.
In February, the spacecraft Perseverance released the first audio clip of Mars that the rover was able to capture. The clip was the sound of a light wind.
Tests conducted by a team of scientists from Los Alamos National Laboratory, a facility of the US Department of Energy in New Mexico, based on data collected by the spacecraft "Perseverence", revealed that higher pitched sound travels on the surface of Mars faster than lower pitches, something that has never been done before. seen or observed elsewhere.
