Henry Ussher (astronomer)
Henry Ussher (1741–1790) was an Irish mathematician and astronomer, best known as the inaugural Andrews Professor of Astronomy at Trinity College Dublin (TCD), a title later accompanied with the designation Royal Astronomer of Ireland. Ussher was a key player in the setting up of Dunsink Observatory outside the city of Dublin, and was its first director. Life Henry was the fourth son of Samuel Ussher, rector of Dunganstown, County Wicklow, by his wife Frances Walsh. Elected a Scholar of Trinity College Dublin in 1759, he graduated B.A. in 1761, M.A. in 1764, B.D. and D.D. in 1779. He was elected to a fellowship in 1764, and co-opted senior fellow in 1781. He was Donegall Lecturer in Mathematics at TCD 1769-1770. Appointed on 22 Jan 1783, the first Andrews Professor of Astronomy, Ussher went to London to order instruments for the planned Dunsink Observatory from Jesse Ramsden.

Andrews Professor Of Astronomy
The Andrews Professor of Astronomy is a chair in astronomy in Trinity College Dublin was established in 1783 in conjunction with the establishment of Dunsink Observatory. Dunsink was founded in 1785 following a bequest by Provost Francis Andrews in 1774, which also funded the professorship. It was regulated by a new Statute of Trinity College Dublin, which required the professor to "make regular observations of the heavenly bodies ... and of the sun, moon and planets". The chair was suspended in 1921 and in 1947 the observatory passed to Dublin Institute for Advanced Studies. In 1984 the professorship was revived as an honorary title in the Department of Pure and Applied Mathematics. From 1793, under letters patent of King George III, the Andrews Professor held the title Royal Astronomer of Ireland. This title fell vacant in 1921 and has not been revived.

18th-century Irish Astronomers
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

At the time, it was known as the Year of the Consulship of Aurelius and Veru (or, less frequently, year 932 ''Ab urbe condita''). The denomination 179 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
