William Crabtree
William Crabtree (1610–1644) was an astronomer, mathematician, and merchant from Broughton, then in the Hundred of Salford, Lancashire, England. He was one of only two people to observe and record the first predicted transit of Venus in 1639. Life and work Crabtree was born in 1610 in the hamlet of Broughton Spout, which was on the east bank of the River Irwell, near the area now known as "The Priory" in Broughton, Salford and was educated at the Manchester Grammar School. He married into a wealthy family and worked as a merchant in Manchester. In his spare time, his great interest was astronomy. He carefully measured the movements of the planets and undertook precise astronomical calculations. With improved accuracy, he rewrote the existing Rudolphine Tables of Planetary Positions. Crabtree corresponded with Jeremiah Horrocks, another enthusiastic amateur astronomer, from 1636. A group of astronomers from the north of England, which included William Gascoigne, fo ...

The Manchester Murals
''The Manchester Murals'' are a series of twelve paintings by Ford Madox Brown in the Great Hall of Manchester Town Hall and are based on the history of Manchester. Following the success of Brown's painting ''Work'' he was commissioned to paint six murals for its Great Hall. Another six murals were to be completed by Frederic Shields who later withdrew, leaving Brown to complete all twelve works. The murals were begun in 1879, towards the end of Brown's career, but were not completed until 1893, the year he died. During this period he moved from London to Manchester with his family, first living in Crumpsall and then Victoria Park. Location The murals form part of the decoration of the Great Hall, the central room designed by Alfred Waterhouse. On entering the hall, six murals are on the left hand wall and six on the right, progressing chronologically from the left wall nearest the entrance to the right wall opposite, repeating the basic structure of the scheme of William Be ...

Ford Madox Brown
Ford Madox Brown (16 April 1821 – 6 October 1893) was a British painter of moral and historical subjects, notable for his distinctively graphic and often Hogarthian version of the Pre-Raphaelite style. Arguably, his most notable painting was ''Work'' (1852–1865). Brown spent the latter years of his life painting the twelve works known as '' The Manchester Murals'', depicting Mancunian history, for Manchester Town Hall. Early life Brown was the grandson of the medical theorist John Brown, founder of the Brunonian system of medicine. His great-grandfather was a Scottish labourer. His father Ford Brown served as a purser in the Royal Navy, including a period serving under Sir Isaac Coffin and a period on HMS ''Arethusa''. He left the Navy after the end of the Napoleonic Wars. In 1818, Ford Brown married Caroline Madox, of an old Kentish family. Brown's parents had limited financial resources, and they moved to Calais to seek cheaper lodgings, where their daught ...

Astronomer Royal
Astronomer Royal is a senior post in the Royal Households of the United Kingdom. There are two officers, the senior being the Astronomer Royal dating from 22 June 1675; the junior is the Astronomer Royal for Scotland dating from 1834. The post was created by King Charles II in 1675, at the same time as he founded the Royal Observatory Greenwich. He appointed John Flamsteed, instructing him "." The Astronomer Royal was director of the Royal Observatory Greenwich from the establishment of the post in 1675 until 1972. The Astronomer Royal became an honorary title in 1972 without executive responsibilities and a separate post of Director of the Royal Greenwich Observatory was created to manage the institution. The Astronomer Royal today receives a stipend of 100 GBP per year and is a member of the Royal Household, under the general authority of the Lord Chamberlain. After the separation of the two offices, the position of Astronomer Royal has been largely honorary, though the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flamsteed
John Flamsteed (19 August 1646 – 31 December 1719) was an English astronomer and the first Astronomer Royal. His main achievements were the preparation of a 3,000-star catalogue, ''Catalogus Britannicus'', and a star atlas called ''Atlas Coelestis'', both published posthumously. He also made the first recorded observations of Uranus, although he mistakenly catalogued it as a star, and he laid the foundation stone for the Royal Greenwich Observatory. Life Flamsteed was born in Denby, Derbyshire, England, the only son of Stephen Flamsteed and his first wife, Mary Spadman. He was educated at the free school of Derby and at Derby School, in St Peter's Churchyard, Derby, near where his father carried on a malting business. At that time, most masters of the school were Puritans. Flamsteed had a solid knowledge of Latin, essential for reading the scientific literature of the day, and a love of history, leaving the school in May 1662.Birks, John L.

Manchester Cathedral
Manchester Cathedral, formally the Cathedral and Collegiate Church of St Mary, St Denys and St George, in Manchester, England, is the mother church of the Anglican Diocese of Manchester, seat of the Bishop of Manchester and the city's parish church. It is on Victoria Street in Manchester city centre and is a grade I listed building. The former parish church was rebuilt in the Perpendicular Gothic style in the years following the foundation of the collegiate body in 1421. Then at the end of the 15th century, James Stanley II (warden 1485–1506 and later Bishop of Ely 1506–1515) was responsible for rebuilding the nave and collegiate choir with high clerestory windows; also commissioning the late-medieval wooden internal furnishings, including the pulpitum, choir stalls and the nave roof supported by angels with gilded instruments. The collegiate church became the cathedral of the new Diocese of Manchester in 1847. It was extensively refaced, restored and e ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the Tropical year, solar year. adoption of the Gregorian calendar, Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic Church, Catholic countries and subsequently in Protestantism, Protestant countries of the Western Christianity, Western Christian world.

Venus
Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth at dark conditions and being visible to the naked eye in broad daylight. Venus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a very weak induced magnetosphere. The atmosphere of Venus, mainly consists of carbon dioxide, and is the densest and hottest of the four terrestrial planets at the surface. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of , the carbon dioxide gas at Venus's surface is in th ...

Solar System
The Solar System Capitalization 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 gravitationally bound system of the Sun and the objects that orbit it. It formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority (99.86%) of the system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter. The four inner system planets— Mercury, Venus, Earth and Mars—are terrestrial planets, being composed primarily of rock and metal. The four giant planets of the outer system are ...
