An aurora (plural: auroras or aurorae ), also known as the polar
lights or aurora polaris, is a natural light display in Earth's sky,
predominantly seen in high-latitude regions (around the Arctic and
Antarctic). Auroras display dynamic patterns of brilliant lights that
appear as curtains, rays, spirals or dynamic flickers covering the
entire sky.The word "aurora" is derived from the name of the Roman
goddess of the dawn, Aurora, who travelled from east to west
announcing the coming of the sun. Ancient Greek poets used the name
metaphorically to refer to dawn, often mentioning its play of colours
across the otherwise dark sky (e.g., "rosy-fingered dawn"). Even
leaving aside the northern lights, travelling to Iceland is an
incredible place to visit, an island of stunning glaciers, massive
geysers, pristine waterfalls and fascinating Viking history. But in
terms of where it sits on the globe, the country is an aurora viewing
jackpot. The weather doesn’t always cooperate, but Iceland’s famous
coastal drive lets you chase clear skies. Perhaps the best aurora
viewing happens on the west coast. When a lightshow is at its peak,
you can even spy Lights from Reykjavík’s suburbs: The Grotta
Lighthouse is a popular local spot to try for a look.
