An interactive walking tour exploring the concept of distance, scale and the sounds of the universe.
Isn’t space silent? Not if we know how to listen. With the right equipment we can use our ears as well as our eyes to probe the cosmos. The universe is full of sounds. Telescopes allow us to capture radio waves emitted by stars across the galaxy and turn them into noises we can hear. And space is not – as popular misconception would have it – an empty “vacuum”. Gas and dust, albeit in small volumes, floats between the stars and can conduct sound waves back to us, such as from the rippling shearing surface of our sun.
Have a listen for yourself here, from the rattling of our atmosphere, to the eerie shrieks and whistles of the moons of Jupiter, to the buzzing chords of nebular clusters – out to the farthest reaches of space and the deepest note in the universe.
