M16/Pillars of Creation Sonification
In the “Pillars of Creation” piece, the sounds are generated by moving horizontally across the image from left to right as seen in both optical and X-ray light. As with the sonification of the Galactic Center, the vertical position of the recorded light controls the pitch, but in this case it varies over a continuous range of pitches. Particular attention is paid to the structure of the pillars which can be heard as sweeps from low to high pitches and back. The two different "melodies" of optical and X-ray light can be enjoyed individually or simultaneously.

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).
