On June 7, 2021, NASA’s Juno spacecraft made its closest flyby of Jupiter’s moon Ganymede, the largest moon in the solar system. The frozen Jovian moon is larger than planet Mercury, and it’s the only natural satellite in the solar system with a magnetic field. While zooming past, Juno recorded Ganymede’s electromagnetic waves and revealed what the moon’s soundtrack is like, reports Michelle Starr for Science Alert.
A 50-second audio track—featuring a wide range of eerie, whistle-like noises—was released during the 2021 American Geophysical Union Fall meeting, after researchers first converted it to a frequency humans can actually hear, reports Jody Serrano for Gizmodo.
Flying at 41,600 miles per hour, Juno swooped 645 miles above Ganymede’s surface to capture the audio, per Science Alert. Juno’s Waves instrument captured the track by measuring radio and plasma waves in Jupiter’s magnetosphere. The Waves instrument was designed to help scientists understand how the planet’s magnetic field, atmosphere, and magnetosphere interact.
