Antarctica's Darkest Period: The Polar Night

Antarctica experiences its most profound darkness during the austral winter, roughly from mid-May to mid-August. During these months, the sun remains below the horizon across most of the continent, creating a continuous polar night. At the South Pole itself, the sun sets at the March equinox and does not rise again until the September equinox—six months of unbroken darkness, broken only by moonlight, auroras, and the stars.
