Data Sonification: Vela Pulsar (Composite)

The Vela Pulsar data has also been converted to sound through a process called data sonification. In this sonification, listen to a radar-like scan, clockwise from 12:00 of the image. Brightness is mapped to volume. Distance from the center is mapped to pitch (farther away is higher pitch). For the Chandra X-ray data, the bright inner region (violet) is mapped to a low synth sound, with 11 Hz oscillations matching the period of the pulsar. The dimmer outer region (blue) and jet are mapped to a wind-like sound. A long upper jet can be heard around 4 seconds in, and a bright, but much shorter lower jet can be heard around 20 seconds. For the Hubble optical data, the stars are mapped to notes on a plucked-type synth (where brighter stars are louder, and stars farther from the center are higher pitched).
