What is the Aurora Borealis?
The aurora borealis, also known as the northern lights, is a mesmerizing natural light display in the Earth’s sky, typically seen in high-latitude regions near the Arctic. This celestial phenomenon occurs when charged particles from the sun, carried by the solar wind, interact with the Earth’s magnetic field and collide with gases in the upper atmosphere. The result is a dazzling display of dancing lights in shades of green, pink, purple, and blue.
Forecasting the Northern Lights
While the aurora borealis is a frequent occurrence in areas like Alaska, northern Canada, Greenland, Iceland, and Scandinavia, it can sometimes be visible at lower latitudes during periods of intense solar activity. To increase your chances of witnessing this breathtaking spectacle, it’s essential to consult reliable aurora forecasts.
