Here's how a black hole sounds, NASA calls it "cosmic music"
NASA has converted light waves echoing from black hole into sound waves.
Black holes have always been one of the most mysterious formations of the universe. These massive celestial bodies, whose gravitational field is so strong that they do not allow any material formation and radiation to escape from them, continue to be researched by astronomers and scientists. During these researches, NASA has shared a video where they employed a sonification technique which help convert the light waves of black hole into sound wave.
NASA shared new sonification of black hole in the V404 Cygni system
NASA's latest sonification shows waves of X-rays observed to echo around a black hole in the V404 Cygni system. Sonification has been done using data from NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory, both of which probe into the X-ray wavelength.
Data from the optical wavelength comes from the Pan-STARRS telescope in Hawaii. Taken together, it is possible to see X-ray waves radiating outward from a point with a black hole at its centre. The black hole itself is rendered invisible because it absorbs all light.
While listening to the sonification, you can hear the melodic sounds of the background stars, each star visible in the optical wavelength is converted into a note, and the pitch and pitch of the note corresponds to the brightness of the star. On top of that, you can also hear the sizzling sound of bursts of X-ray radiation forming rings around the black hole.
NASA explained that this V404 Cygni system is 7,800 light-years away from our planet and it has a black hole with a mass that ranges to ten times that of the Sun.
