Sagittarius A* Sonification
This image shows the region around the Milky Way's central supermassive black hole, known as Sagittarius A* (Sgr A*), in infrared (orange and purple) and X-ray light (blue). The image is scanned from left to right and the data are transformed into sound. The brightness of the objects is represented by the volume, while the vertical positions of the sources in the image are mapped to musical pitches. X-rays are played with a soft synthesizer and the infrared data are heard as bass notes and plucked sounds. The brightest region in the middle of the image (and hence the loudest) is where Sgr A* the black hole, resides. It is within this area that the Event Horizon Telescope was able to peer to obtain the first image of Sgr A* itself.

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).
