NASA's Voyager 1 Detect Strange Sound from Space

NASA's Voyager 1 spacecraft, launched in 1977, is famous for its interstellar journey beyond our solar system. While it doesn't have the capability to record sound in the vacuum of space (as sound requires a medium like air to travel through), Voyager 1 has provided valuable data about the plasma waves and electromagnetic fields it encounters in interstellar space. These data can be converted into audible frequencies, creating "sounds" that represent the interactions between the spacecraft and its environment. These are often referred to as "sounds of space," but they are not true sounds as we typically think of them. Instead, they are data sonifications, allowing scientists and the public to "hear" the data in a meaningful way. These recordings have revealed fascinating information about the density of particles and magnetic fields in the distant regions of our galaxy. While they may be described as "strange" to our ears, they are invaluable tools for scientific discovery.
