7 of the most stunning natural phenomena around the world

The aurora, commonly referred to as the northern and southern lights, is a stunning display of green, purple, blue, and red lights that shimmer across the sky. This natural phenomenon occurs when charged particles from the sun interact with the Earth's magnetic field and atmosphere. The aurora is most visible in the polar regions, where the magnetic field is strongest and the nights are long and dark. The ideal time to witness the aurora is during the winter months when solar activity is at its peak and the skies are clear.
