The Hubble Ultra Deep Field in Light and Sound
Explanation:
Have you heard about the Hubble Ultra-Deep Field?
Either way, you've likely not
heard about it like this --
please run your cursor over the featured image and listen!
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.
One of the most famous images in astronomy, the
HUDF 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 red end of the
spectrum of light,
they are depicted here by a shift of tone toward the low end of the
spectrum of sound.
The further the galaxy, the greater its
cosmological redshift
(even if it appears blue), and the lower the tone that will be played.
The average galaxy in the
HUDF
is about 10.6 billion
light years away and sounds like an
F#.
What's the
most distant galaxy you can find?
Note: Sounds will only play on some browsers.
