Earth is emitting mysterious radiation after sunset and scientists cannot explain why

A newly discovered, faint radio emission, the Hectometric Continuum, emerges only after sunset and pulses through Earth's upper atmosphere for several hours. This natural radiation, undetectable from the ground, originates from plasma interactions within the magnetosphere and has surprised scientists due to its nighttime-only appearance and sensitivity to calm space weather.
