This is an invitation to commune with the sun.
The video contains imagery from NASA’s Solar Dynamics Observatory in five wavelengths of ultraviolet light. Scrubbing left to right reveals new layers, from sunspots on the solar surface to prominences extending outward in the corona.
The audio is the solar wind: more than six decades of OMNI hourly speed measurements, audified and played as one continuous file. Each data sample is mapped to an audio sample. Dragging up and down will raise and lower the playback speed, modulating the low hum of solar spherical harmonics. Dragging left and right controls the cutoff frequency of a bandpass filter.
This page was created by Dr. Robert Alexander, a solar sonification specialist. Check out his showcase on the NASA YouTube page, and read more about his work here or connect on LinkedIn.
