What sound can teach us about our Sun? In this episode, we explore how NASA scientists translate electromagnetic waves from the Sun into sound, and even music. Through this process, researchers are gradually unlocking the Sun’s secrets, from the steady “hum” of the star’s rotation, to the way that solar winds “play” the Earth’s magnetosphere like a harp. This story comes from the podcast NASA’s Curious Universe, and features Host and Astrophysicist Padi Boyd, Sonification Specialist Robert Alexander and Heliophysicist Mike Hartinger.
