Angell Hall Observatory
Angell Hall Observatory is an astronomical observatory owned and operated by University of Michigan. It is located on the UM Central Campus on top of Angell Hall in Ann Arbor, Michigan (US). It has a computer-controlled 0.4-m Cassegrain telescope in its single dome, and a small radio telescope on the roof. In the past it has housed a large, clock-driven refracting telescope and a reflecting telescope in side-by-side domes. The current telescope was manufactured by DFM Engineering and installed in December 1994. Other observatories that UM has operated include the Detroit Observatory (1854), the Lamont–Hussey Observatory (South Africa, 1928), the McMath–Hulbert Observatory (Lake Angelus, Michigan, 1930), the Portage Lake Observatory (near Dexter, Michigan, 1948), and the Peach Mountain Observatory (near Dexter, Michigan, 1958).

McMath–Hulbert Observatory
The McMath-Hulbert Solar Observatory is a solar observatory in Lake Angelus, Michigan, USA. It was established in 1929 as a private observatory by father and son Francis Charles McMath and Robert Raynolds McMath and their friend, Judge Henry Hulbert. In 1932 the observatory was deeded to the University of Michigan which operated it until 1981, at which time it was sold into private ownership again. In 1932 a reflector telescope was added to the observatory as well as a spectroheliokinematograph . This instrument was designed to take motion pictures of the Sun. The McMath-Hulbert Solar Observatory is primarily known for the motion pictures that the McMaths made of various celestial phenomena, including the first movies of solar prominences in motion. Later work involved solar spectroscopy in the near infrared and participation in a solar flare patrol program in the 1950s. Robert McMath and one of the resident astronomers, Keith Pierce, established the McMath–Pierce solar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Michigan Campus
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde' ...

Astronomical Observatories In Michigan
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, profess ...

List Of Observatories
This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dexter, Michigan
Dexter is a city in Washtenaw County in the U.S. state of Michigan. The population was 4,067 at the 2010 census. Dexter Township is located to the northwest and does not border the city, and the two are administered autonomously. The township and city are named for Samuel William Dexter, the founder of the village and the first circuit judge of Washtenaw County. History The area was first settled in 1824, 13 years before Michigan became a state, when land speculator Samuel W. Dexter purchased a large tract of land and originated the village. It was known as "Mill Creek Settlement" until the village was platted in 1830, when its name was officially changed to Dexter. Mill Creek and the Huron River, which form much of the western and northeastern boundaries of the city, respectively, have long been valuable resources to Dexter. A sawmill was built in 1827, a woolen mill in 1838, a grist mill in 1844, and a cider mill in 1886. After being appointed County Court Justice i ...

Lake Angelus, Michigan
Lake Angelus is a city in Oakland County in the U.S. state of Michigan. It is an affluent suburb of Detroit, with one of the highest per capita incomes of any community in the state. History In the early 1900s, a small community formed around the lake, then called Three Mile Lake. During the 1920s, the lake was renamed Lake Angelus by Mrs. Sollace B. Collidge as the original name stood for the distance from the eastern side of the lake shore to the western shore. The community was under pressure from nearby government establishments to be annexed. In 1929, however, a special state act of legislation was passed, granting Lake Angelus incorporation as a village. Lake Angelus became a city of its own in 1984. Geography According to the United States Census Bureau, the city has a total area of , of which is land and (34.36%) is water. The city completely surrounds the lake of the same name. The city is bordered: * To the north and east by the city of Auburn Hills * To the south b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
