A Minnesota Planetarium Video- Natural Radio: When solar flares hit the Earth's magnetic field, the skies at both poles can light up with auroras. The particles also create very low frequency electromagnetic waves, a type of natural radio that can be picked up around the globe. Every year sound recordist Steve McGreevy heads north where the reception is best and points his receiver at the sky.
