Objects Visible From Space
Artificial structures visible from space without magnification include highways, dams, and cities.Cecil Adams, "Is the Great wall of China the only manmade object you can see from space?", ''The Straight Dope'', found aThe Straight Dope website Accessed 12 May 2010.Snopes, "Great wall from space", last updated 21 July 2007, found aSnopes.com archives Accessed 12 May 2010. The Great Wall of China, often cited as the only human-made structure visible from space, is not visible from low Earth orbit without magnification, and even then can be seen only under perfect conditions. On the other hand, the centimetre-band Spaceborne Imaging Radar of STS-59 and STS-68 was able to detect not only the Great Wall but also invisible buried segments of it. Whether an object is visible depends significantly on the height above sea level from where it is observed.

Heavens-Above
Heavens-Above is a non-profit website developed and maintained by Chris Peat as ''Heavens-Above GmbH''. The web site is dedicated to helping people observe and track satellites orbiting the Earth without the need for optical equipment such as binoculars or telescopes. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen during a pass. Special attention is paid to the ISS, Starlink satellites, and others. Space Shuttle missions were tracked until the program was retired in July 2011 and Iridium flares were also tracked until the program was retired in May 2018. The website also offers information on currently visible comets, asteroids, planet details, and other miscellaneous information. ''Sky & Telescope'' magazine described Heavens-Above as "the most popular website for tracking satellites." Users click on a map of the world to set their viewing location.

Porphyry Copper Deposit
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic fluids. Successive envelopes of hydrothermal alteration typically enclose a core of disseminated ore minerals in often stockwork-forming hairline fractures and veins. Because of their large volume, porphyry orebodies can be economic from copper concentrations as low as 0.15% copper and can have economic amounts of by-products such as molybdenum, silver, and gold. In some mines, those metals are the main product. The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the introduction of steam shovels, the construction of railroads, and a surge ...

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...

Bingham Canyon Mine
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than . The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over deep, wide, and covering . It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andalucía
Andalusia (, ; es, Andalucía ) is the southernmost Autonomous communities of Spain, autonomous community in Peninsular Spain. It is the most populous and the second-largest autonomous community in the country. It is officially recognised as a Nationalities and regions of Spain, "historical nationality". The territory is divided into eight Provinces of Spain, provinces: Province of Almería, Almería, Province of Cádiz, Cádiz, Province of Córdoba (Spain), Córdoba, Province of Granada, Granada, Province of Huelva, Huelva, Province of Jaén (Spain), Jaén, Province of Málaga, Málaga, and Province of Seville, Seville.

Province Of Almería
Almería (, also , ) is a province of the autonomous community of Andalusia, Spain. It is bordered by the provinces of Granada, Murcia, and the Mediterranean Sea. Its capital is the homonymous city of Almería. Almería has an area of . With 701,688 (2014) inhabitants, its population density is 79.96/km2, slightly lower than the Spanish average. It is divided into 103 municipalities. Geography The highest mountain range in the Province of Almería is the long Sierra de Los Filabres. Europe's driest area is found in Almería and is part of the Cabo de Gata-Níjar Natural Park. The arid landscape and climate of the province have made it an ideal setting for Western films, especially during the 1960s. Because of the demand for these locations, quite a number of Western towns were built near the Tabernas Desert. Films such as ''A Fistful of Dollars'', '' For a Few Dollars More'', and ''The Good, The Bad, and The Ugly'' were shot here. Years later, the film of ''800 Bullets'' was f ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

Chernobyl Nuclear Power Plant
The Chernobyl Nuclear Power Plant (ChNPP; ; ), is a nuclear power plant undergoing decommissioning. ChNPP is located near the abandoned city of Pripyat in northern Ukraine northwest of the city of Chernobyl, from the Belarus–Ukraine border, and about north of Kyiv. The plant was cooled by an engineered pond, fed by the Pripyat River about northwest from its juncture with the Dnieper. ChNPP was commissioned in phases with the four reactors entering commercial operation between 1978 and 1984. In 1986, reactor No. 4 was the site of the Chernobyl disaster; as a result of this, the power plant is now within a large restricted area known as the Chernobyl Exclusion Zone. Both the zone and the power plant are administered by the State Agency of Ukraine on Exclusion Zone Management. The three other reactors remained operational post-accident maintaining a capacity factor between 60 and 70%. In total, units 1 and 3 had supplied 98 terawatt-hours of electricity each, with unit 2 slig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
