NASA recently published this visualization of Space being ‘sonified’ as Music from Space. Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 acquired this image on Aug. 13, 2018, which shows a cluster of galaxies imaged by Hubble. Most of the visible specks are galaxies housing countless stars. A few individual stars shine brightly in the foreground.
Are really hearing music from space?
When played, the timeline moves left to right and the frequency of sound changes from bottom to top, ranging from 30 to 1,000 Hertz. Objects near the bottom of the image produce lower notes/frequencies, while those near the top produce higher ones.
Stars and compact galaxies create short, clear tones, while sprawling spiral galaxies emit longer notes that change pitch.

NASA also recently posted in the “Astronomy Picture of the Day“, one of the most famous images in astronomy, the HUDF, which is featured here in a vibrant way — with sonified distances
Pointing to a galaxy will play a note that indicates its approximate redshift. Because redshifts shift light toward the low red end of the spectrum of light, they are depicted here by a shift of tone towards the low end of the spectrum of sound.

The Hubble Ultra-Deep Field (HUDF) was created in 2003-2004 with the Hubble Space Telescope staring for a long time toward near-empty space so that distant, faint galaxies would become visible.
