sonified astronomical interferometry
Modern radio astronomy allows us to see farther into the cosmos than ever before. The second image below is the GaLactic and Extragalactic All-sky Murchison Widefield Array survey (GLEAM) of the Milky Way galaxy taken by Dr. Natasha Hurley-Walker and her team at the Murchison Widefield Array in Western Australia. By tapping into radio waves they are able to identify distant star forming regions, supernova remnants, and radio galaxies beyond our own in the electromagnetic spectrum—matter, events, and other cosmic readings that the comparatively narrow band of visible light cannot see.


This recorded radio data, called visiblities, is turned into an image via a Fourier transform. But, what does it sound like? What are its temporal qualities? This installation seeks to give that radio data such materiality.
