Utqiaġvik (Ut-qi-ag-vik) in Alaska recently witnessed its last sunrise of 2018. The city will now witness sunrise after a period of 65 days. The northernmost city in the United States experiences 'polar nights' during the winter season. The phenomenon is a result of the Earth's tilt away from the Sun.'Civil twilight' will engulf the city for the next 2 months where a little illumination will allow residents to see things outside.
