‘Polar night’ arrives in Utqiagvik, Alaska, bringing 66 days of darkness

If you’re afraid of the dark, the United States’ northernmost town might not be for you. In Utqiagvik, Alaska, formerly known as Barrow, the sun will set for the last time in 2020 on Wednesday. The next time it rises, more than two months will have elapsed, the calendar will have flipped to 2021, and a new president will occupy the White House.

The extended darkness soon to settle in is courtesy of “polar night,” a phenomenon at high latitudes that visits the Arctic and Antarctic circles each winter. Because of Earth’s tilt on its axis, regions in the Arctic Circle can remain facing away from the sun for days, weeks or even months at a time between the fall and spring equinoxes.
The opposite is true in the summertime, when brightness reigns 24 hours a day in the “land of the midnight sun.”
