Studying space is all about translating signals into meaningful information.<\/p>\n
Most of the signals we receive from the cosmos are part of the electromagnetic spectrum \u2013 and human vision is limited to a relatively narrow range of that spectrum. Other signals can be measurements of waves in plasma<\/a>, or gravitational ripples in the very fabric of spacetime<\/a>.<\/p>\n The way information is encoded in radio waves or light transmitted by optical fiber for human communication is a good way to think about it. On their own, these signals carry no inherent meaning to our senses; they must first be decoded, or translated into a form we can interpret.<\/p>\n In astronomy, much of the data we receive is translated into a visual medium. This serves extremely well when we’re dealing with light. But waves travel through space in various ways \u2013 and in some cases, it makes more sense to translate the data into sound.<\/p>\n For some efforts, such as NASA’s data sonification project<\/a>, that translation consists of a direct conversion of image data into sound \u2013 points of light turned into musical notes.<\/p>\n For others, it’s a matter of taking wave data and mapping it into audible frequencies. That can be pressure waves propagating through hot gas around a supermassive black hole<\/a>, or plasma waves<\/a> along the lines of Earth’s magnetic field.<\/p>\n Each body in the Solar System produces its own idiosyncratic soundscape<\/a>.<\/p>\n The Sun, for instance, would be positively roaring<\/a> as its surface roils with constantly rising and sinking convection cells larger than the state of Texas.<\/p>\n Scientists have estimated that, if sound could propagate through space, we could hear the Sun as a constant roar hammering at around an ear-bursting 100 decibels<\/a>.<\/p>\n Saturn<\/a> and Jupiter<\/a>, with their complex systems of rings and moons, produce signals that, when translated, sound like the eerie music of alien cultures.<\/p>\n The very first sounds from space were recorded by astronomer Karl Guthe Jansky in 1933. He built a rotating radio telescope nicknamed Jansky’s Merry-Go-Round<\/a>, designed to detect a specific frequency range of radio waves.<\/p>\n When his data started coming in, there was a persistent background hiss that, Jansky discovered, was not random noise<\/a>, but the radio emission from the heart of the Milky Way galaxy itself<\/a>.<\/p>\n![\"Subscribe](\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/03\/Generic-Health-Promo-Final-642x273.jpg\")
