Supernova Sonata by Alex Parker From April, 2003 until August, 2006, the
Canada-France-Hawaii Telescope watched four parts of the sky as often as possible. Armed with the largest digital camera in the known universe, CFHT monitored these four fields for a special type of
supernova (called Type Ia) which are created by the thermonuclear detonation of one or more
white-dwarf stars. Each supernova is assigned a note to be played:
The volume of the note is determined by the distance to the supernova, with more distant supernova being quieter and fainter.
The pitch of the note was determined by the supernova’s “stretch,” a property of how the supernova brightens and fades. Higher stretch values played higher notes. The pitches were drawn from a
Phrygian dominant scale.
The instrument the note was played on was determined by the properties of the galaxy which hosted each supernova. Supernovae hosted by massive galaxies are played with a stand-up bass, while supernovae hosted by less massive galaxies are played with a grand piano.
