The magnetosphere of Ganymede, the Jupiter’s largest moon, is a source of electric and magnetic radio emissions, which have been monitored by the Waves instrument onboard NASA’s Juno spacecraft. The 50-second audio track was generated from data collected during Juno’s close flyby of Ganymede on June 7, 2021. Juno’s Waves instrument, which tunes in to electric and magnetic radio waves, collected the data on those emissions. “The Juno trajectory approached Ganymede on its corotational wake hemisphere (orbital leading hemisphere),” said lead author Dr. William Kurth, a researcher at the University of Iowa, and colleagues.
