A short audio feature. Broadcast on Resonance FM on 19th July 2013.

The skies are never silent.

Invisible to the naked eye, VLF, or Very Low Frequency radio waves, are the sonic equivalent to the stunning visual aurorae that illuminate the planet's poles. Caused by the interaction of solar energy with the charged part of the Earth's atmosphere, they can only be made audible with special equipment.

This audio feature blends original recordings of VLF sounds with the voices of those who work with them, from science to sound art, King's Cross to California.
