True polar night is limited to latitudes above roughly 84° 34' North or South, which is exactly 18° within the polar circles, or approximately five and a half degrees from the poles. The only permanent settlement on Earth at these latitudes is the Amundsen–Scott scientific research station in Antarctica , whose winter personnel are ...
During the six-month polar night, air temperatures can drop below −73 °C (−99 °F) and blizzards are more frequent. Between these storms, and regardless of the weather for wavelengths unaffected by drifting snow, the roughly 5 + 3 ⁄ 4 months of ample darkness and dry atmosphere make the station an excellent site for astronomical ...

Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
Star Gazers (formerly known as Jack Horkheimer: Star Hustler and later Jack Horkheimer: Star Gazer) is a short astronomy show on American public television previously hosted by Jack Horkheimer, executive director of the Miami Space Transit Planetarium.
