Our Universe is a place so amazingthat sometimes things turn out to be reality, which many could not even think of. Remember Giordano Bruno? At one time, he was the only person who dared to suggest that our world is much more than just the Earth and the Sun. As we know today, Bruno was right: our Universe is full of dishonest number of planets, stars, unsolved mysteries and even mysterious black holes. And yet there is one thing that does not exist in space: sound. Without the molecules of the earth's air that help us hear, there, in space, all that can be heard is absolute silence. Perhaps better than others, Stanley Kubrick could illustrate this in the 2001 Odyssey. Fortunately, the frightening space silence did not prevent NASA experts from figuring out how to get sound in space. We tell how they succeeded.
We do not hear the cosmos, as our earsperceive air vibrations, and space - an airless environment. But thanks to the existence of electromagnetic waves, which freely propagate in vacuum, X-ray and gamma radiation, ultraviolet light, visible light, infrared radiation and radio waves, we can reproduce what is happening in space.
Sounds of space
So it turned out that space is not always soundless -NASA experts found a way to get sound in complete, it would seem, silence, back in 2019. This was made possible thanks to the "sounding" of the image made by the Hubble Space Telescope, which recently celebrated its 30th birthday. Yes, today we can not only look at distant galaxies, but also listen to them.
Image that NASA experts have chosen forThis project was obtained with the help of the advanced for shooting the Hubble space telescope camera and the wide-angle camera installed back in August 2018. Scientists who work directly with Hubble call the resulting image a “galactic treasure chest” due to the number of galaxies scattered across it.
It's interesting: NASA introduced the visualization of a black hole
According to Science Alert, scientists say thatevery spot visible in the photograph is a galaxy that is home to countless stars. So, a few stars closer to us shine brightly in the foreground, while a massive cluster of galaxies nests in the very center of the image. The giant assembly, perhaps thousands of galaxies, is held together by the unforgiving force of gravity.
Let me remind you that gravity is a kind ofDirector General of the cosmos - it is she who controls all the events that occur on the open spaces of the bottomless cosmic ocean. In fact, for the thirty years of the existence of the Hubble Space Telescope, we are so used to looking at images obtained with its help that translating photos into sound really seems something fantastic. But there’s something else you need to know - this space music sounds at least creepy.

A team of scientists who worked to createsound image, explains that different places and elements in the photo produce different sounds. So, stars and small galaxies are represented by short and clear sounds, while spiral galaxies emit more complex, longer notes.
Time flows from left to right, and the frequency of soundvaries from bottom to top, varying from 30 to 1000 Hertz. Objects located at the bottom of the image produce lower notes, while objects located at the top of the image produce higher notes.

NASA's explanations in the comments accompanying the NASA video.
And although at first the music may seemthe eerie actually “sounds” of this picture create a pretty beautiful melody, especially closer to the middle when the sound reaches a cluster of galaxies called RXC J0142. 9 + 4438. That's why, they say at the National Space Agency, that a higher density of galaxies near the center of the image leads to a surge in mid tones in the middle of the video. Well, are you ready to hear how distant galaxies sound in the vastness of an infinitely expanding universe?
So here it is - a whole new way to enjoy the universe:
In fact, the sounds of space are not somethingincredible. Of course, if a person is in outer space, he will not hear anything, but thanks to science and modern tools, we can hear how planets rotate, stars burn, and even asteroids fly. Of course, we all would very much like to go on a safe space journey, during which we could hear space objects. And in fact, today we have such an opportunity - science and the ship of imagination, as the astrophysicist and planetarium director Hayden and New York neil Degrass Tyson aptly pointed out, work wonders.
