Aurora Borealis: The aurora borealis, or northern lights, is a mesmerizing natural light display that occurs in the northern hemisphere’s night sky. Caused by charged particles from the sun interacting with the Earth’s magnetic field, the auroras take the form of shimmering, dancing curtains of colored light in hues of green, pink, purple, and blue. These ethereal lights shift and move across the sky in undulating waves, creating a hypnotic and otherworldly spectacle. The auroras are most commonly seen in regions closer to the Arctic Circle.
