The Sound of the Sun
The sound of the sun. Scientists measure the changing light waves given off by the sun using an instrument called a dopplergraph that is mounted on a spacecraft called the Solar and Heliospheric Observatory (SOHO). The measured light changes are translated into motion (sound) waves by computer models that capture the relationships between light waves and sound waves.

Permission to use the sound of the sun recording is outlined at the SOHO website.
