The polar lights, known as “Aurora Borealis,” occur only during the freezing nights of the Earth’s polar regions. Just like stars, polar lights occur during the day, as well, though we cannot see them due to interference from sunlight. The duration of the polar lights varies from half a minute to more than half an hour. The moving speed of the polar lights is also highly variable, and their kaleidoscopic nature creates the most unforgettable of sights and experiences one may have in a lifetime.
