He participated in the construction of an observatory at the Louvre.

The observatory is able to accommodate up to eight visitors in basic self-catering accommodation which can be booked through Manx National Heritage.

The institute's primary task is to carry out basic research, education and associated observatory activities in space physics, space technology and atmospheric physics.

The observatory offers basic camping facilities.

Having become assistant to Carlos Guillermo Moesta ( 1825 – 1884 ), director of the observatory at Santiago de Chile, in 1859, he was associated with the Chilean geodesic survey in 1864.

From 1869 to 1872, he was employed as an Assistant in Harvard's astronomical observatory, doing important work on determining the brightness of stars and the shape of the Milky Way.

For the last 23 years of his life astronomy, Lowell Observatory, and his and others ' work at his observatory were the focal points of his life.

In former times, before the distribution of accurate time signals, it was part of the routine work at any observatory to observe the sidereal times of meridian transit of selected ' clock stars ' ( of well-known position and movement ), and to use these to correct observatory clocks running local mean sidereal time ; but nowadays local sidereal time is usually generated by computer, based on time signals.

The scientific work of the observatory was relocated elsewhere in stages in the first half of the 20th century, and the Greenwich site is now maintained as a tourist attraction.

While this was being constructed, von Miller was also working at the Zeiss factory with German astronomer Max Wolf, director of the Landessternwarte Heidelberg-Königstuhl observatory of the University of Heidelberg, on a new and novel design, inspired by Wallace W. Atwood's work at the Chicago Academy of Sciences and by the ideas of Walther Bauersfeld at Zeiss.

* Copernicus ' astronomical observatory, work room, instruments and planetarium are on display at Frombork's Copernicus Museum

The observatory was established in 1945 by Sir Bernard Lovell, who wanted to investigate cosmic rays after his work on radar during the Second World War.

The mounting in 1859 of an equatorial of 330 mm ( 13 inch ) aperture evoked the comment in his journal for that year, " There is not now a single person employed or instrument used in the observatory which was there in Mr Pond's time "; and the transformation was completed by the inauguration of spectroscopic work in 1868 and of the photographic registration of sunspots in 1873.

The Danish survey was then in progress, and he acted as Schumacher's assistant in work connected with it, chiefly at the new observatory of Altona, 1821 – 1825.

He had started to work as an assistant to Johann Franz Encke in 1835 immediately following the completion of the Berlin observatory.

He stood down as an Assembly Member in 2003 to work on a research project to study the inner workings of the sun from the observatory near the North Pole.

In 1881, Pickering hired Fleming to do clerical work at the observatory.

Some years after he had finished his study he started work at the Leidse Sterrewacht ( Leiden observatory ), where he wrote his thesis.

Reade served as incumbent until 1859, establishing a school and an astronomical observatory, and performing pioneering work in the early development of photography.

Year-round meteorological observatory and the northernmost cosmic rays station work in the town too.

In 1907, he became director of the Paris Observatory where he immediately set to work to relaunch the stalled Carte du Ciel project with a conference held at the observatory, entertained by singers from the Paris Opera and refreshed by wine provided by the director of the Bordeaux Observatory.

; Later observatory work

It took Struve five years of hard work to include the observatory to the Russian leveling network.

The centre features interactive exhibits about astronomy, the work of the observatory and its parent organization, the NRC Herzberg Institute of Astrophysics.

After the death of baron Parish in 1858, his heirs had the observatory of Senftenberg dismantled and the astronomical instruments sold although Brorsen offered to continue his work for free.

However, the role of Klinkerfues ' section of the observatory was solely to deal with practical work, the theoretical work being placed in the hands of Ernst Schering.

In 1864 he started to work for the observatory, and received his Ph. D. in 1868 working on methods to obtain the latitude of a place by astronomical observations.

In 1813, he suffered the disruptions of the Napoleonic Wars: his work was ruined by the French under Vandamme, who destroyed his books, writings and observatory.

Only the Earth-orbiting missions remained, namely the Orbital Workshop and Apollo Telescope Mount solar observatory.

The summit observatory, which is located at an altitude of, is an important scientific measuring station operated by the Institute for Meteorology and Climate Research of Karlsruhe Institute of Technology.

It uses the word observatory, from astronomy, to emphasize a degree of detachment and objectivity in measuring well-being.

This instrument is capable of sensing vertical displacements as small as 0. 1 mm, by measuring the change in gravity as the observatory moves closer to or further from the Earth's center.

The principal line of work of the observatory consisted of determination of coordinates of stars and astronomical constants, such as precessions, nutations, aberrations and refractions, and also discovering and measuring double stars.

From 1882 to 1925 Juvisy-sur-Orge was the location of the astronomer Camille Flammarion's observatory, as well as the 1740 Pyramid erected to memorialize the work of Jean Picard and Nicolas Louis de Lacaille in measuring the Earth's circumference.

The cost will be split between NASA and Department of Energy. The satellite observatory would be capable of measuring up to 2, 000 distant supernovae each year of its three-year mission lifetime.

The observatory consists of fourteen major geometric devices for measuring time, predicting eclipses, tracking stars ' location as the earth orbits around the sun, ascertaining the declinations of planets, and determining the celestial altitudes and related ephemerides.

As it covered only the northern sky and some of the south ( being compiled from the Bonn observatory ), this was then supplemented by the Südliche Durchmusterung ( SD ), which covers stars between declinations-1 and-23 degrees

The observatory was launched on 12 December 1970 into an initial orbit of about 560 km apogee, 520 km perigee, 3 degrees inclination, with a period of 96 minutes.

Both observatory sites provided full azimuthal coverage ( 360 degrees in azimuth ).

The large field of view of the Canon lenses gives each observatory a massive sky coverage of just under 500 square degrees per pointing.

In medieval Islamic astronomy, the Zij-i Ilkhani compiled at the Maragheh observatory set the precession of the equinoxes at 51 arc seconds per annum, which is very close to the modern value of 50. 2 arc seconds.

Having succeeded to his father's position at the observatory in 1712, he measured in 1713 the arc of the meridian from Dunkirk to Perpignan, and published the results in a volume entitled Traité de la grandeur et de la figure de la terre ( 1720 ).

Between 1816 and 1852, the observatory completed the famous survey triangulation measurements of the angular arc ( named Struve Geodetic Arc ).
