Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north- and south poles. The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole ...
Observed south dipoles during 1903–2000 are yellow squares. IGRF-12 Modeled pole locations from 1590 to 2020 are circles progressing from blue to yellow. [1] The south magnetic pole, also known as the magnetic south pole, is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed perpendicular to the nominal ...
South Pole telescope during polar night. The green light is the southern lights. During winter (May through August), the South Pole receives no sunlight at all, and is completely dark apart from moonlight. In summer (October through February), the sun is continuously above the horizon and appears to move in a counter-clockwise circle.
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 pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an amplified event of a true polar wander. Geologically, a surface shift ...
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]
Karen Kylleso accomplished the feat overnight between Monday and Tuesday, 114 years after fellow Norwegian and polar explorer Roald Amundsen became the first person to reach the South Pole.
The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic field (because opposite magnetic poles attract and the north end of a magnet, like a compass needle, points toward Earth's South ...
