Voice One: This is what scientists say the sun sounds like--- the equivalent of a solar heartbeat. Solar scientists used listening devices to unravel some of the mysteries of Earth’ s nearest star. It’ s not the actual sound. Sound can’ t travel through the vacuum of space. But [this is] a recreation based on the waves recorded by the devices.
Each pitch corresponds with the movement and vibrations of various hot gasses as they flow like rivers beneath the sun’ s surface--- similar to how trade winds blow on Earth.
Scientists translate the sounds they make into images. This allows a unique glimpse inside the sun’ s complex architecture, to answer questions about its temperature, chemical makeup, and how gasses inside ebb and flow.
Voice Two: What we’ re finding is that there are very interesting structures inside. There’ s an equatorial belt of faster moving material. And then, farther up near the poles, we believe that there’ s a jet stream of material moving about 60 miles an hour up at a very north latitude.
