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.
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres).
2020 — 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, and is located approximately a half billion light-years away.
South Polar Group, South Galactic Pole Group [4] The Sculptor Group is a loose group of galaxies [ 2 ] [ 3 ] visible near the south galactic pole. [ 1 ] The group is one of the closest groups of galaxies to the Local Group ; the distance to the center of the group from the Milky Way is approximately 3.9 Mpc (12.7 Mly ).
A number of different coordinate systems, each differing by a few degrees, were used until 1932, when Lund Observatory assembled a set of conversion tables that defined a standard galactic coordinate system based on a galactic north pole at RA 12 h 40 m, dec +28° (in the B1900.0 epoch convention) and a 0° longitude at the point where the ...
Galaxies and galaxy clusters < 50 M ly away from Earth plotted in the supergalactic plane. The supergalactic coordinate system is a reference frame for the supercluster of galaxies that contains the Milky Way galaxy, referenced to a local relatively flat collection of galaxy clusters used to define the supergalactic plane.
Kirk was a passionate leader, and Spock’s logical, emotionless demeanor helped manage the Captain’s drive and vision, making them an ideal fit for their galactic missions. Image credits: Paramount
Discovery of the South Pole Wall (2020). [25] The South Pole Wall is a large scale structure observed in the direction of the south celestial pole. With its heart located in the Chamaeleon constellation, this filament embraces the southernmost frontiers of the Laniakea supercluster. It is roughly the same size as the Sloan Great Wall, at half ...
