How are they created? Solar winds are sent from the Sun’s outer layer and then travel quickly towards the Earth at speeds of up to 45 million miles per hour. Our planet’s magnetic field redirects these waves and sends them towards the poles. There they mix with nitrogen and oxygen gases in the air. When combined with the winds, nitrogen gases tend to create red waves of light and oxygen produces green ripples in the sky. Due to shorter days in winter, this season is thought to be the best time to see the lights.Did You Know...? In 2018, the Parker Solar Probe was sent into space to study the Sun and solar winds.
