This program delves into the sounds of Earth's magnetosphere and ionosphere. With the Earth’s magnetic field acting as a natural waveguide, both man-made signals and natural phenomena can be heard in across the radio spectrum. Using radio as translator, invisible phenomena manifest as auditory experiences, allowing a glimpse at the unseen electromagnetic tapestry that surrounds each of us in our daily lives.

Featured sounds: lightning (spherics and whistlers), cosmic background radiation, the Earth’s magnetic field, space weather, radar, auroras, meteors, sun storms, and the magnetic field that protects the Earth from solar radiation, the Van Allen Belt.
