A projection of the South Pole Wall in celestial coordinates. The South Pole Wall (SPW or The South Pole Wall) is a massive cosmic structure formed by a giant wall of galaxies (a galaxy filament) that extends across at least 1.37 billion light-years of space, the nearest light (and consequently part) [a] of which is aged about half a billion light-years.
In one system, the U axis is directed toward the Galactic Center (l = 0°), and it is a right-handed system (positive towards the east and towards the north galactic pole); in the other, the U axis is directed toward the galactic anticenter (l = 180°), and it is a left-handed system (positive towards the east and towards the north galactic ...
The South Pole is by definition the southernmost point on the Earth, lying antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been ...
In astronomy, coordinate systems are used for specifying positions of celestial objects (satellites, planets, stars, galaxies, etc.) relative to a given reference frame, based on physical reference points available to a situated observer (e.g. the true horizon and north to an observer on Earth's surface).

The President of Chile visits the south pole in January 2025. In 1991, Michael Palin visited the base on the eighth and final episode of his BBC Television documentary, Pole to Pole. [40] [41] On January 10, 1995, NASA, PBS, and NSF collaborated for the first live television broadcast from the South Pole, titled Spaceship South Pole. [42]
A galactic orientation describes the spatial orientation of a galactic plane, where such exists for a given galaxy.For a spiral galaxy, this can be obtained from the inclination of the galactic plane to the plane of the sky, and the position angle of the major axis as viewed from Earth.
Immediately next to the BICEP telescope at the Martin A. Pomerantz Observatory building at the South Pole was an unused telescope mount previously occupied by the Degree Angular Scale Interferometer. [28] The Keck Array was built to take advantage of this larger telescope mount.
An azimuthal equidistant projection about the North Pole extending all the way to the South Pole An azimuthal equidistant projection about the South Pole extending all the way to the North Pole Emblem of the United Nations containing a polar azimuthal equidistant projection. The azimuthal equidistant projection is an azimuthal map projection.
