Known as the solar wind, this incessant stream of plasma, or electrified gas, has pelted Earth for more than 4 billion years. Thanks to our planet’s magnetic field, it’s mostly deflected away. Most of Earth is shielded from the solar wind, but right near the poles, in the midday sector, our magnetic field becomes a funnel where the solar wind can get all the way down to the atmosphere. These funnels, known as the polar cusps, can cause some trouble. The influx of solar wind disturbs the atmosphere, disrupting satellites and radio and GPS signals.
