HUBBLE ULTRA DEEP FIELD

This is a sonification of Hubble's iconic Ultra Deep Field image. We start from Earth and imaging flying out into the image. A note is triggered for every galaxy we pass as we travel out to a distance of 13 billion light years. The musical pitch indicates the overall colour of the galaxy with redder light being lower notes and bluer light being higher notes. You can hear the steep drop in pitch towards the end since the farthest galaxies in the image are extremely redshifted due to the expansion of the universe.
