About the northern lights aurora borealis Search Trend

The northern lights, or aurora borealis, are natural light displays in Earth's polar skies caused by charged solar particles colliding with atmospheric gases. They arise when solar wind interacts with Earth's magnetosphere, exciting oxygen and nitrogen atoms at altitudes from about 60 to 300 kilometers to emit colorful glows (green, red, purple). They are most commonly seen at high latitudes, including Alaska, Canada, Scandinavia, and parts of the northern United States, with stronger geomagnetic storms occasionally pushing visibility to states like Oregon and Maine; viewing conditions improve on clear, dark nights away from city lights, especially in winter. In recent years, episodes of intensified solar activity and coronal mass ejections have produced vivid auroras during strong storms, prompting NOAA space weather forecasts and aurora alerts to help observers plan.
