The Royal Observatory, Greenwich is an observatory situated on a hill in Greenwich Park in east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passes through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and Cutty Sark are collectively designated Royal Museums Greenwich.

The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Cerro Pachón about 10 kilometres (6.2 mi) to the southeast. It is within the Coquimbo Region and approximately 80 kilometres (50 mi) east of La Serena, where support facilities are located. The site was identified by a team of scientists from Chile and the United States in 1959, and it was selected in 1962. Construction began in 1963 and regular astronomical observations commenced in 1965. Construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope in 1974, but smaller facilities have been built since then. Cerro Pachón is still under development, with two large telescopes inaugurated since 2000, and one in the early stages of construction.
The Center for Astrophysics | Harvard & Smithsonian (CfA) is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory. Founded in 1973 and headquartered in Cambridge, Massachusetts, the CfA leads a broad program of research in astronomy, astrophysics, Earth and space sciences, as well as science education. The CfA either leads or participates in the development and operations of more than fifteen ground- and space-based astronomical research observatories across the electromagnetic spectrum, including the forthcoming Giant Magellan Telescope (GMT) and the Chandra X-ray Observatory, one of NASA's Great Observatories.
The Črni Vrh Observatory is an astronomical observatory located in western Slovenia, close to the settlement of Črni Vrh, near the town of Idrija. The current observatory was built in 1985 and stands at an elevation of 730 metres (2,400 ft). Much of the construction was done by volunteers.
The Fick Observatory was an astronomical observatory owned and operated by Iowa State University. Located southwest of Boone, Iowa it was named after Davenport, Iowa amateur astronomer Erwin W. Fick. The observatory closed in 2015.
The Special Astrophysical Observatory of the Russian Academy of Science is an astronomical observatory, set up in 1966 in the USSR, and now operated by the Russian Academy of Sciences. Based in the Bolshoi Zelenchuk Valley of the Greater Caucasus near the village of Nizhny Arkhyz, the observatory houses the BTA-6 and RATAN-600, an optical and radio telescope, respectively. The two instruments are about 20 km (12 mi) apart.
Leuschner Observatory, originally called the Students' Observatory, is an observatory jointly operated by the University of California, Berkeley and San Francisco State University. The observatory was built in 1886 on the Berkeley campus. For many years, it was directed by Armin Otto Leuschner, for whom the observatory was renamed in 1951. In 1965, it was relocated to its present home in Lafayette, California, approximately 10 miles (16 km) east of the Berkeley campus. In 2012, the physics and astronomy department of San Francisco State University became a partner.
The Warner and Swasey Observatory is the astronomical observatory of Case Western Reserve University. Named after Worcester R. Warner and Ambrose Swasey, who built it at the beginning of the 20th century, it was initially located on Taylor Road in East Cleveland, Ohio, USA. The observatory, which at that time housed a 9.5-inch (24 cm) refractor, was donated in 1919 to the Case School of Applied Science. The newer 24-inch (61 cm) Burrell Schmidt telescope was built in 1939.
Ashton Observatory is a public astronomical observatory operated by the Des Moines Astronomical Society, in collaboration with Jasper County, Iowa (USA). It is located in Ashton-Wildwood County Park near Baxter, Iowa. Public programs are presented on Saturday evenings in the months of April through October, except for the first Saturday of each month. These public nights have been cancelled for 2020, due to the Covid-19 pandemic.
Grant Oscar Gale was the S.S. Williston Professor of physics at Grinnell College in Grinnell, Iowa, the curator of Grinnell's Physics Historical Museum, and the namesake of the Grant O. Gale Observatory on the Grinnell campus.
Rutherfurd Observatory is the astronomical facility maintained by Columbia University named after Lewis Morris Rutherfurd. Initially, Rutherfurd housed its telescopes and equipment in midtown Manhattan and later on the Stuyvesant Estate. When the Morningside campus was built, telescopes were kept in a "transit building" where the Interdisciplinary Science Building now stands. When Pupin Physics Laboratories were completed in 1927, the home of the observatory was moved to the top of the building. Below the Rutherfurd Observatory on the 14th floor was the site of Professor Wallace Eckert's Astronomical Laboratory, in which he constructed the first device to perform general scientific calculations automatically in 1933-34.
Fuertes Observatory is an astronomical observatory located on the North Campus of Cornell University in Ithaca, New York. The observatory was designed by L.P. Burnham, Cornell Professor of Architecture and completed in fall of 1917. It was originally used by the Civil Engineering Department as an instructional field office for navigation and surveying. Today, the observatory is primarily used for public outreach, welcoming over two thousand visitors per year with open houses on clear Friday nights.
The Lulin Observatory is an astronomical observatory operated by the Institute of Astronomy, National Central University in Taiwan.
The RUM Planetarium is the first planetarium in Puerto Rico. It is located in the fourth floor of the Physics building of the University of Puerto Rico at Mayagüez in Mayagüez, Puerto Rico.
The Dark Sky Observatory (DSO) is an astronomical observatory owned and operated by Appalachian State University (ASU). It is located 9 kilometers (5.6 mi) east of Deep Gap, North Carolina (USA), off of the Blue Ridge Parkway, and 32 kilometers (20 mi) east of the ASU campus in Boone, North Carolina It was established in 1981, and is used for research, instruction, and public viewing events. The Cline Visitors' Center was completed in 2011.
Yerkes 41-inch reflector is a 40-inch aperture (101.6 cm) reflecting telescope at the Yerkes Observatory, that was completed in 1968. It is known as the 41 inch to avoid confusion with a 40 inch refractor at the observatory. Optically it is a Ritchey–Chrétien design, and the main mirror uses low expansion glass. The telescope was used as a testbed for an adaptive optics system in the 1990s.
