The aurora lights, also known as the northern lights (aurora borealis) or southern lights (aurora australis), are a natural light display in the sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic). They appear as shimmering curtains, rays, spirals, or flickers of light, often in various colors like green, pink, purple, and white.

The aurora lights are caused by the
interaction of charged particles from the sun with atoms in Earth's
atmosphere. When these particles collide with atoms, they excite the atoms,
causing them to emit light. The color of the light depends on the type of atom
that is excited.
The aurora lights are most commonly seen in
the auroral zones, which are located around the magnetic poles of Earth. The
best time to see them is during the equinoxes (March and September) when the
nights are longer and the auroral activity is higher. However, they can be
seen at other times of the year as well, especially during periods of high
solar activity.
