National Astronomical Observatory (Chile)
The National Astronomical Observatory of Chile (Spanish: ''Observatorio Astronómico Nacional de Chile'' - OAN) is an astronomical observatory owned and operated by the Department of Astronomy of the University of Chile (UCh). It is located on Cerro Calán, a hill in the commune of Las Condes. The commune is an eastern suburb of Santiago located in Santiago Province of the Santiago Metropolitan Region. OAN was founded in 1852 and became a part of UCh in 1927. The facility on Cerro Calán was completed in 1962. History OAN can be traced back to the Gillis Expedition, a project of the United States Naval Observatory. Led by James Melville Gilliss, it arrived in Chile in 1849 to observe Mars and Venus from the southern hemisphere so as to improve solar parallax. Gilliss and his party set up their equipment on Santa Lucia Hill, a small rise in downtown Santiago. After completing the project in 1852, Gilliss sold the equipment and the buildings that housed it to the governme ...

National Astronomical Observatories Of China
The National Astronomical Observatories, Chinese Academy of Sciences (NAOC, ) is an astronomical research institute operated by Chinese Academy of Sciences, along with Shanghai Astronomical Observatory, Purple Mountain Observatory and National Time Service Center. History and introduction Founded on April 25, 2001, NAOC was formed through the merging of four Chinese Academy of Sciences (CAS) observatories, three CAS observing stations and one CAS research centre. The Headquarters of the NAOC are situated in the northern Chaoyang District of Beijing on the site of the former Beijing Astronomical Observatory (BAO), and take responsibility for all matters relating to the former BAO. Currently, NAOC has 7 astronomical research departments listed follows: * Optical Astronomy Research Department (光学天文研究部) * Radio Astronomy Research Department (射电天文研究部) * Galactic Astronomy & Cosmology Research Department (星系宇宙学研究部) * Moon & Deep Space Det ...

List Of Astronomical 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 atmo ...

National Astronomical Observatory Of Japan
The (NAOJ) is an astronomical research organisation comprising several facilities in Japan, as well as an observatory in Hawaii and Chile. It was established in 1988 as an amalgamation of three existing research organizations - the Tokyo Astronomical Observatory of the University of Tokyo, International Latitude Observatory of Mizusawa, and a part of Research Institute of Atmospherics of Nagoya University. In the 2004 reform of national research organizations, NAOJ became a division of the National Institutes of Natural Sciences. Facilities ;Mitaka Campus (Mitaka, Tokyo. ) :The Headquarters, Astronomy Data Center, Advanced Technology Center, Public Relations Center :Solar Flare Telescope, Sunspot Telescope, TAMA 300 gravitational wave detector :Tokyo Photoelectric Meridian Circle :Historical instruments: Solar Tower Telescope, 65cm refractor dome, 20cm refractor dome ;Nobeyama Radio Observatory (Minamimaki, Nagano, ) :45m Millimeter Radio Telescope, Nobeyama Radio Polarim ...

National Astronomical Observatory (Mexico)
The National Astronomical Observatory (Spanish: ''Observatorio Astronómico Nacional''—OAN) is an astronomical observatory in Baja California, Mexico. History Mexico City The observatory was first established on the balcony of Chapultepec Castle in Mexico City in 1878. The observatory has been operated by the National Autonomous University of Mexico (UNAM) since 1929. It was later moved to Palacio del Ex-Arzobispado in Tacubaya, then on the outskirts of the city on the west side of the Federal District. The location is remembered by the name Metro Observatorio, the terminal station of the Line 1 of the Mexico City Metro located nearby. Puebla In the middle of the 20th century, OAN had to move from the increasingly crowded and polluted Valley of Mexico, to Tonantzintla in Puebla state, Central Mexico. Baja California In 1967 excessive air pollution and night light pollution caused another move, from Puebla to atop the Sierra San Pedro Mártir mountain range of Baja Cali ...

National Astronomical Observatory (Spain)
The Spanish National Observatory ( es, Observatorio Astronómico Nacional de España, OAN) is an astronomical observatory with several facilities in the Madrid area. The Observatory has published a yearbook (the ''Anuario del Observatorio Astronómico de Madrid'') since the 19th century. Royal Observatory The seat of the National Observatory is the Royal Observatory ( es, Real Observatorio Astronómico de Madrid) in the Parque del Buen Retiro. This historic observatory was built in 1790. Equipped with a Herschel telescope, it took over the purely astronomical work of the naval observatory, the ''Real Instituto y Observatorio de la Armada'', in the south of the country. The building was designed by Juan de Villanueva and represents one of the highlights of Spanish neoclassical architecture. Its domed lantern was conceived as a classical circular temple. The Observatory houses historic scientific equipment and can be visited by prior arrangement. There is also a library. Yebes ...
