Edward Joshua Cooper
Edward Joshua Cooper (May 1798 – 23 April 1863) was an Irish landowner, politician and astronomer from Markree Castle in County Sligo. He sat in the House of Commons of the United Kingdom from 1830 to 1841 and from 1857 to 1859, but is best known for his astronomy, and as the creator of Markree Observatory. His observatory was home to the largest refracting (telescope with a lens) of the 1830s (an almost 14 inch astronomical grade Cauchoix of Paris lens, the largest in the World), and the asteroid 9 Metis was discovered there in the 1840s by his assistant. Several astronomical catalogs were also produced in the 19th century there. Early life and family Cooper was the oldest son of Edward Synge Cooper MP (1762–1830), and his wife Anne Verelst, daughter of Bengal Governor Harry Verelst (colonial governor), Harry Verelst.

North Cape, Norway
The North Cape (; ) is a cape on the northern coast of the island of Magerøya in Northern Norway. The cape is in Nordkapp Municipality in Finnmark county, Norway. The European route E69 motorway (highway) has its northern terminus at the North Cape, which makes it the northernmost point in Europe that can be accessed by car and makes the E69 the northernmost public road in Europe. The plateau is a popular tourist attraction. The cape includes a with a large flat plateau on top, where visitors, weather permitting, can watch the midnight sun and views of the Barents Sea to the north. North Cape Hall, a visitor centre, was built in 1988 on the plateau. It includes a café, restaurant, post office, souvenir shop, a small museum, and video cinema. Geography The steep cliff of the North Cape is located at , about from the North Pole. Nordkapp is often inaccurately referred to as the northernmost point of Europe. However, the neighbouring Knivskjellodden Cape actually extends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slieve Gullion
Slieve Gullion ( or ''Sliabh Cuilinn'', "Culann's mountain") is a mountain in the south of County Armagh, Northern Ireland. The mountain is the heart of the Ring of Gullion and is the List of Irish counties by highest point, highest point in the county, with an elevation of . At the summit is a small lake and two ancient cairn, burial cairns, one of which is the highest surviving passage grave in Ireland. Slieve Gullion appears in Irish mythology, where it is associated with the Cailleach and the heroes Fionn mac Cumhaill and Cú Chulainn. It dominates the countryside around it, offering views as far away as County Antrim, Dublin Bay and County Wicklow on a clear day. Slieve Gullion Forest Park is on its eastern slope.

Board Of Ordnance
The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in the 18th century. By the 19th century, the Board of Ordnance was second in size only to HM Treasury among government departments. The Board lasted until 1855, at which point (tarnished by poor performance in supplying the Army in Crimean War, Crimea) it was disbanded. Origins of the Board The introduction of gunpowder to Europe led to innovations in offensive weapons, such as cannon, and defences, such as fortifications. From the 1320s a member of the Royal Households of the United Kingdom, Royal Household, the 'Keeper of the Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrew Graham (astronomer)
Andrew Graham (8 April 1815 – 5 November 1908) was an Irish astronomer, orbit computer and discoverer of the asteroid 9 Metis."Report of the Observatory Syndicate on the Chief Assistant at the Observatory." Cambridge, England: Cambridge University, 23 May 1903. Astronomer at Markree, County Sligo In 1842 Graham was appointed to work at Markree Observatory in County Sligo in northwest Ireland. The observatory had been established in 1830 by Colonel Edward Joshua Cooper (1798–1863) as a private institution on his country estate. Cooper equipped it with excellent astronomical instruments. Graham proved an energetic observer at Markree. Graham discovered the asteroid 9 Metis from Markree on 25 April 1848 while observing with a 3-inch aperture wide-field telescope manufactured for comet searching by the German instrument maker Ertel. Only eight minor planets were known before then, with the first four having been found in the period 1801–1807, and Graham's discove ...

Comet-seeker
A comet seeker is a type of small telescope adapted especially to searching for comets: commonly of short focal length and large aperture, in order to secure the greatest brilliancy of light. This style of telescope was used to discover the asteroid 9 Metis in 1848. Design A comet seeker telescope is a type of optical device that is known for having a short focal length but a wide field of view. Examples A comet seeker with about 3.9 inch aperture was installed at the United States Naval Observatory in 1843, and later transferred to the Smithsonian Museum in 1866. It had an aperture of 4 inches (10.2 cm) and was made by Utzschneider & Fraunhofer in Munich. This was operated as part of suite of several other instruments including a larger refractor on an equatorial mounting, a meridian transit, mural circle, etc. Markree Observatory added a 3-inch aperture Comet Seeker on an equatorial mount by Ertel. It was ordered in 1842, and in place until 1874. The Markree Comet Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meridian-circle
The meridian circle is an instrument for timing of the passage of stars across the local meridian, an event known as a culmination, while at the same time measuring their angular distance from the nadir. These are special purpose telescopes mounted so as to allow pointing only in the meridian, the great circle through the north point of the horizon, the north celestial pole, the zenith, the south point of the horizon, the south celestial pole, and the nadir. Meridian telescopes rely on the rotation of the sky to bring objects into their field of view and are mounted on a fixed, horizontal, east–west axis. The similar transit instrument, transit circle, or transit telescope is likewise mounted on a horizontal axis, but the axis need not be fixed in the east–west direction. For instance, a surveyor's theodolite can function as a transit instrument if its telescope is capable of a full revolution about the horizontal axis. Meridian circles are often called by these names, althou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to Ecliptic, the plane of Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In #Types, partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Mo ...

Halley's Comet
Halley's Comet is the only known List of periodic comets, short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years, though with the majority of recorded apparitions (25 of 30) occurring after 75–77 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC, but it was not until 1705 that the English astronomer Edmond Halley understood that these appearances were re-appearances of the same comet. As a result of this discovery, the comet is named after Halley. During its 1986 visit to the inner Solar System, Halley's Comet became the first comet to be observed in detail by a spacecraft, ''Giotto (spacecraft), Giotto'', providing the first obser ...

Description Of The Equatorial Mounting Of Mr
Description is any type of communication that aims to make vivid a place, object, person, group, or other physical entity. It is one of four rhetorical modes (also known as ''modes of discourse''), along with exposition, argumentation, and narration. Fiction writing Fiction writing specifically has modes such as action, exposition, description, dialogue, summary, and transition. Author Peter Selgin refers to ''methods'', including action, dialogue, thoughts, summary, scenes, and description. Description is the mode for transmitting a mental image of the particulars of a story. Together with dialogue, narration, exposition, and summarization, it is one of the most widely recognized of the fiction-writing modes. As stated in ''Writing from A to Z'', edited by Kirk Polking, it is more than the amassing of details; it is bringing something to life by carefully choosing and arranging words and phrases to produce the desired effect.

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Grubb
Thomas Grubb (4 August 1800 – 16 September 1878) was an Irish optician and founder of the Grubb Telescope Company. He was born near Portlaw, County Waterford, Ireland, the son of William Grubb Junior, a prosperous Quaker farmer and his second wife, Eleanor Fayle. Thomas started out in 1830 in Dublin as a metal billiard-table manufacturer. He diversified into making telescopes and erected a public observatory near his factory at 1 Upper Charlemont Street, Portobello, Dublin. As makers of some of the largest and best-known telescopes of the Victorian era, the company was at the forefront of optical and mechanical engineering. His innovations for large telescopes included clock-driven polar mounts, whiffletree mirror mounting cells and Cassegrain reflector optics. Later, the manufacturing firm changed its name to Grubb-Parsons in 1925. Works Thomas Grubb's reputation as a competent telescope maker began to spread as he offered his talents to the Irish astronomical comm ...
