What does the Milky Way sound like? The Chandra Data Sonification project transforms data from the NASA Chandra X-ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope into sound so that stargazers can "listen" to the Galactic Center of the Milky Way, the supernova Cassiopeia A, and the "Pillars of Creation" star-forming region of the Messier 16 "Eagle Nebula." Each telescope detects a different wavelength and is represented in the sonification by a different instrument. "X-ray" (represented by xylophone) comes from heated gas from stellar explosions detected by Chandra. "Optical" (violin) is produced by energetic star-forming regions detected by Hubble. "Infrared" (piano) emanates from glowing clouds of dust detected by Spitzer. The "Composite" is a symphony of all three wavelengths. The position and intensity of light determines the pitch and volume of each instrument. Listeners can scroll the landing page to find a brief video on how data sonification works. The project was developed by the Chandra X-ray Center (previously featured in the 01-16-2009 Scout Report) as part of NASA's Universe of Learning program.
