Milky Way (Antarctica)
The Milky Way is a col (a gap between two mountain peaks) situated between the southernmost extremity of the LeMay Range and the Planet Heights mountain range, in the eastern part of Alexander Island, Antarctica. It is the highest point on a possible sledging route between Jupiter Glacier and Uranus Glacier. The col was first mapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by D. Searle D. or d. may refer to, usually as an abbreviation: * Don (honorific), a form of address in Spain, Portugal, Italy, and their former overseas empires, usually given to nobles or other individuals of high social rank. * Date of death, as an abbreviati ... of the Falkland Islands Dependencies Survey in 1960. It was named after the Milky Way by the UK Antarctic Place-Names Committee from association with the nearby Planet Heights and the glaciers which are named for the planets of the Solar System.

LeMay Range
The LeMay Range () is a mountain range long with peaks rising to , extending in a northwest–southeast direction from Snick Pass to the north side of Uranus Glacier in the central portion of Alexander Island, Antarctica. It was first seen from the air by Lincoln Ellsworth on November 23, 1935, and the north and east portions mapped from photos obtained on that flight by W.L.G. Joerg. Later, it was resighted from the air by the Ronne Antarctic Research Expedition (RARE), 1947–48, and named by Finn Ronne for General Curtis LeMay, Deputy Chief of Air Staff for Research and Development of the then United States Army Air Forces, which furnished equipment for the expedition. The range was remapped in detail from RARE photos by D. Searle of the Falkland Islands Dependencies Survey in 1960.

Planet Heights
Planet Heights () is a series of summits running along an ice-free ridge, extending 24 nautical miles (44 km) in a north-south direction between the southernmost extremity of the LeMay Range and George VI Sound in the east part of Alexander Island, Antarctica. Many landforms and nearby features are named in association with this mountain range; some of these include landforms named after astronomers, satellites, planets and other things related to astrology and astrophysics. The mountain range was first mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) from association with the nearby glaciers named for planets of the Solar System. The only planet that is not featured in any of these glaciers is the planet Earth, as there are no glaciers named "Earth Glacier" and this glacier does not exist. Glacie ...

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jupiter Glacier
Jupiter Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, which flows east into George VI Sound to the south of Ablation Valley. It was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition, and was named for the planet Jupiter by the Falkland Islands Dependencies Survey following their surveys in 1948 and 1949. The glacier lies north of Planet Heights, although Jupiter Glacier is not situated within the mountain range, the glacier (along with many other nearby glaciers named after planets of the Solar System) is so named under the association of Planet Heights even though it is not directly a glacier located within this mountainous range.

Uranus Glacier
Uranus Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, flowing east into George VI Sound immediately south of Fossil Bluff. Along the south face of the glacier is an east–west escarpment called Kuiper Scarp. The glacier was probably first seen by Lincoln Ellsworth, who flew directly over it and photographed segments of this coast on November 23, 1935. The portion near the mouth of the glacier was first roughly surveyed in 1936 by the British Graham Land Expedition. It was named by the United Kingdom Antarctic Place-Names Committee for the planet Uranus following the resurvey of its lower portions by the Falkland Islands Dependencies Survey in 1948 and 1949. Although the glacier is named for a planet of the Solar System The Solar System Capitalization of the name varies.

Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Milky Way
The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term ''Milky Way'' is a translation of the Latin ', from the Greek ('), meaning "milky circle". From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of , but only about 1,000 light years thick at the spiral arms (more at the bulg ...

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravity, gravitationally bound system of the Sun and the objects that orbit it. It Formation and evolution of the Solar System, formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The solar mass, vast majority (99.86%) of the system's mass is in the Sun, with most of the Jupiter mass, remaining mass contained in the planet Jupiter.
