Albert Le Sueur
Adolphus Albert Le Sueur (8 December 1849 – 25 April 1906), often known as Albert Le Sueur, was an astronomer known for his early involvement with the Great Melbourne Telescope and his preliminary use of astronomical spectroscopy. This information seems to be at odds with official records Adolphus Albert Le Sueur (as listed) was born and died on this dates but for him to Matriculated in 1859 means he would have been 10 years old which seems debatable. Also official documents of Adolphus' show his parents were Phillipe Le Sueur and Rachel Bazin .Therefore additional research needs to be done to confirm the link between Adolphus and Albert - it seems they are separate people.

Great Melbourne Telescope
The Great Melbourne Telescope was built by Thomas Grubb in Dublin, Ireland in 1868, and installed at the Melbourne Observatory in Melbourne, Australia in 1869. In 1945 that Observatory closed and the telescope was sold and moved to the Mount Stromlo Observatory near Canberra. It was rebuilt in the late 1950s. In 2003 the telescope, still in use as an observatory, was severely damaged in a bushfire. About 70% of the components were salvageable; a project to restore the telescope to working condition started in 2013. With a 48 inch (1.2 metre) diameter primary mirror, it was one of the largest telescopes of the late 19th century. This is a significant size even into the 21st century, although the lower reflecting ability of speculum metal mirrors (about 2/3 reflected) makes them inferior to later metal-on-glass designs or large refractors. This was significantly larger than the largest refractors of the period such as the Lick telescope and Yerkes, although those were both in the n ...

Astrophotography
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum photons over these long periods of time. Photography using extended exposure-times revolutionized the field of professional astronomical research, recording hundreds of thousands of new stars, and nebulae invisible to the human eye. Specialized and ever-larger optical telescopes were constructed as essentially big cameras to rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alumni Of Pembroke College, Cambridge
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

Jersey People
The Jersey people (Jèrriais: ''Jèrriais''; french: Jersiais, links=no) also referred to as Islanders, are an ethnic group and nation native to the island of Jersey in the Channel Islands who share a common history, Norman ancestry and culture. There is no standard demonym for Jersey people, however common demonyms include Jerseyman/Jerseywoman or Jèrriais. Jersey people are colloquially known as 'beans', after the Jersey bean crock - a traditional meal, or (the Jèrriais word for toad), the reason being that Jersey has toads and Guernsey does not. There is a statue in St. Helier of a toad, known as Le Crapaud. The Jersey toad is a unique species, which are bigger, breed earlier and use different habitats than English toads. Population Jersey is the largest and most populous island of the Channel Islands, an archipelago near the coast of France that is part of the British Isles. Jersey is a British Crown dependency and is not part of the United Kingdom of Great Britain and No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Australian Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Argus (Melbourne)
''The Argus'' was an Australian daily morning newspaper in Melbourne from 2 June 1846 to 19 January 1957, and was considered to be the general Australian newspaper of record for this period. Widely known as a conservative newspaper for most of its history, it adopted a left-leaning approach from 1949. ''The Argus''s main competitor was David Syme's more liberal-minded newspaper, ''The Age''. History The newspaper was originally owned by William Kerr, who was also Melbourne's town clerk from 1851–1856 and had been a journalist at the ''Sydney Gazette'' before moving to Melbourne in 1839 to work on John Pascoe Fawkner's newspaper, the '' Port Phillip Patriot''. The first edition was published on 2 June 1846. The paper soon became known for its scurrilous abuse and sarcasm, and by 1853, after he had lost a series of libel lawsuits, Kerr was forced to sell the paper's ownership to avoid financial ruin. The paper was then published by Edward Wilson. By 1855, it had a daily c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farie Macgeorge
Robert Forsyth Macgeorge (1796 – 26 October 1859) was an early settler of South Australia who is remembered for founding the property which is now the Adelaide suburb of Urrbrae. A number of his children were prominent in the early history of South Australia and other Australian colonies. History Robert Forsyth Macgeorge, a tailor of Glasgow, and his wife Elizabeth M. Macgeorge, née Duncan (1801–) and their family emigrated to South Australia aboard the ''Ariadne'', arriving on 13 August 1839. They developed the property they named "Urr brae", now known as Urrbrae. R. F. Macgeorge took over Shepherd's draper's shop on Hindley Street. On what was intended as a visit to the "Old Country", he narrowly avoided being involved in the '' Admella'' disaster, then perished when the '' Royal Charter'' was wrecked. Family Their children included: *John MacGeorge (1821 – 1 January 1844) died from tuberculosis *Robert Forsyth Macgeorge, Jnr (1822 – 17 September 1917) married Emil ...

Robert Ellery
Robert Lewis John Ellery (14 July 1827 – 14 January 1908) was an English-Australian astronomer and public servant who served as Victorian government astronomer for 42 years. Early life Ellery was born in Cranleigh, Surrey, England, the son of John Ellery, a surgeon, and his wife Caroline, ''née'' Potter. Ellery was educated at the local grammar school and qualified as a medical practitioner, but he had an early interest in astronomy. Friends at Greenwich Observatory encouraged him and he had some access to instruments there. Career Ellery sailed for Victoria in 1851 attracted by the discovery of gold, and is stated to have practised as a physician at Williamstown, Victoria. If so it could only have been for a very short period, as in 1853 the Victorian government decided to found an astronomical observatory as a service to shipping, whose navigators relied critically on accurate astronomical time for determination of their longitude and appreciated the opportunity to synch ...

Melbourne
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dublin
Dublin (; , or ) is the capital and largest city of Republic of Ireland, Ireland. On a bay at the mouth of the River Liffey, it is in the Provinces of Ireland, province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census of Ireland, 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census of Ireland, 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kings of Dublin, Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and e ...
