WASP-96 b Sonification
NASA’s Webb Telescope observed the atmospheric characteristics of the hot gas giant exoplanet WASP-96 b — which contains clear signatures of water — and the resulting transmission spectrum’s individual data points were translated into sound.
The sonification scans the spectrum from left to right. From bottom to top, the y-axis ranges from less to more light blocked. The x-axis ranges from 0.6 microns on the left to 2.8 microns on the right. The pitches of each data point correspond to the frequencies of light each point represents. Longer wavelengths of light have lower frequencies and are heard as lower pitches. The volume indicates the amount of light detected in each data point. The new sounds were also adapted to a video, allowing sighted viewers to watch the progression as the vertical line moves across the graph, ringing out a musical note for each data point.
The four water signatures are represented by the sound of water droplets falling. These sounds simplify the data — water is detected as a signature that has multiple data points. The sounds align only to the highest points in the data.
This sonification does not represent sounds recorded in space. Two musicians converted Webb’s transmission spectrum to musical pitches to help listeners hear its data.

The Chandra sonifications were led by the Chandra X-ray Center (CXC), with input from NASA's Universe of Learning. The sustained collaboration was driven by visualization scientist Dr. Kimberly Arcand (CXC), astrophysicist Dr. Matt Russo and musician Andrew Santaguida (both of the SYSTEM Sounds project).
