He Is Risen On High (Demo)

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note — one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. A new sonification — that is, the translation of astronomical data into sound — is being released in time for NASA’s Black Hole Week this year.

In some ways, this sonification is unlike any other done before because it revisits the actual sound waves discovered in data from NASA’s Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelops the hundreds or even thousands of galaxies within it, providing an avenue for the sound waves to travel.

In this new sonification of Perseus, the sound waves that were previously identified were extracted and made audible for the first time. The sound waves were extracted in radial directions, that is, outwards from the center. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. Another way to put this is that they are being heard 144 and 288 quadrillion (1,000,000,000,000,000) times higher than their original frequency. The radar-like scan around the image allows you to hear waves emitted in different directions. In the visual image of these data, blue and purple both show X-ray data captured by Chandra.

The Stanford Experimental Physics Lab sonified data from the European Space Agency and NASA's Solar and Heliospheric Observatory (SOHO). This humming sound captures the Sun’s natural vibrations and provides scientists with a concrete representation of its dynamic movements.
