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.
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 ...
The term is used for similar photos captured elsewhere, such as on board the International Space Station and on Mars. [ 2 ] [ 3 ] Typical shutter speeds for a star trail range from 15 minutes to several hours, requiring a " Bulb " setting on the camera to open the shutter for a period longer than usual.
Planetary magnetic poles are defined analogously to the Earth's North and South magnetic poles: they are the locations on the planet's surface at which the planet's magnetic field lines are vertical. The direction of the field determines whether the pole is a magnetic north or south pole, exactly as on Earth.
Our compasses are just pointing to one pole at a time because there’s a dominant two-pole system. But sometimes, Earth doesn’t always just have a single magnetic North and South Pole.
The south celestial pole over the Very Large Telescope [3] Locating the south celestial pole. The south celestial pole is visible only from the Southern Hemisphere. It lies in the dim constellation Octans, the Octant. Sigma Octantis is identified as the south pole star, more than one degree away from the pole, but with a magnitude of 5.5 it is ...
A spacecraft has beamed back some of the best close-up photos ever of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above ...
