Upon our little spinning rock,
Cosmic rays and debris knock.
Through great fields and waves we race,
Not empty, our broad path through space!
We’re touched, long fingers from afar:
Energy from our bright star.
A fusing, roiling dynamo,
Magnetic fields induced by flow.
Eleven circuits round our wheel,
Her heartbeat’s pulses we can feel.
In search of answers, models run,
Probing rhythms of the sun.
