Research stations operated by various nations endure weeks or months of darkness. During this period, the sun stays below the horizon, but the sky is not completely dark.
Life in a Sunless Environment: Research and Survival in Perpetual Darkness
When people ask which country has no sun , they are usually referring to a place experiencing extreme seasonal darkness rather than a literal absence of daylight. The extreme cold and isolation make the conditions more severe than in the Arctic, but the scientific community stationed there continues to conduct vital research using specialized equipment to simulate daylight cycles.
At the poles, the sun does not rise for roughly six months, from the September equinox to the March equinox. Residents rely heavily on artificial lighting and adjust their circadian rhythms to maintain normal schedules, proving that life can thrive even when the sun does not visit.

The primary nations experiencing this phenomenon include: Norway Sweden Finland Russia Canada United States (Alaska) Denmark (Greenland) Life in the Dark In northern Norway, towns like Longyearbyen experience polar night from late October to mid-February. Understanding the mechanics of this perpetual night requires looking at the Earth's axial tilt and its orbit around the sun, which create the variations in daylight we experience across different latitudes.
