| There is a world of noise out there, some of it beyond the range of the human ear, some of it just too remote for us to hear it. Below you'll find some of the strangest sounds science has to offer – click on the links to have a listen... |
Horse DNA
DNA doesn’t really make any sound, of course, but researchers at UCLA have figured out a way of interpreting it as a musical score. This particular melody comes from proteins in a horse’s haemoglobin.

The Big Bang
Rumbles from the biggest explosion in history could still be heard in the Universe 700,000 years after the Big Bang went bang. This simulation is based on cosmic microwave data collected by NASA satellites.

Undersea Earthquake

Saturn's Aurorae
When NASA’s Cassini probe recorded radio waves from the solar winds on Saturn, this was the result. The waves are normally inaudible, but when converted to sound and slowed down the frequencies by 44 times, you get this eerie wailing…
