A series of solar flares and coronal mass ejections from the sun are creating dazzling auroras across the globe. The rare solar storm may also disrupt communications. The last time a solar storm of this magnitude reached Earth was in October 2003, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.
Understanding Auroras
Increased solar activity causes auroras that dance around Earth’s poles, known as the northern lights (aurora borealis) and southern lights (aurora australis). When energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere, creating a spectrum of colors in the night sky.
Even when auroras are not visible to the naked eye, photographs of the night sky can capture stunning colors that might otherwise go unnoticed. Below, we showcase some breathtaking images of these celestial phenomena.
