- Data Sonification: M87
- Description
- Space is mostly quiet. Data collected by telescopes are most often turned into silent charts, plots, and images. A "sonification" project led by NASA's Chandra X-ray Observatory and the Universe of Learning transforms otherwise inaudible data from some of the world's most powerful telescopes into sound. This effort makes it possible to experience data from cosmic sources with a different sense: hearing. The giant black hole in Messier 87 (M87 for short) and its surroundings have been studied for many years and by a range of telescopes including Chandra (blue) and the Very Large Array (red and orange). This data shows that the black hole in M87 is sending out massive jets of energetic particles that interact with vast clouds of hot gas that surround it. To translate the X-rays and radio waves into sound, the image is scanned beginning at the 3 o'clock position and sweeping clockwise like a radar. Light farther from the center is heard as higher pitched while brighter light is louder. The radio data are lower pitched than the X-rays, corresponding to their frequency ranges in the electromagnetic spectrum. The point-like sources in X-ray light, most of which represent stars in orbit around a black hole or neutron star, are played as short, plucked sounds.
