Wikipedia notes that observatories have long been built for disciplines including "astronomy, climatology/meteorology, geophysics, oceanography and volcanology," with new instruments continually replacing older ones as technology improves. Browsing by operational start year lets a visitor compare observatories that came online in the same period.Facts20th centurySourcesComments (0)Reader Challenges (0)FactsComparisonField Origin EraWell-attested1608 120th centuryFilter Results64 entriesPlatformAllCosmic Microwave Background Satellites (1)Infrared Space Telescopes (1)Optical Observatories of Africa and Oceania (4)Optical Observatories of Asia and the Middle East (10)Optical Observatories of Europe (8)Optical Observatories of the Americas (16)Optical, Ultraviolet and Exoplanet Space Telescopes (4)Radio and Millimetre Interferometer Arrays (7)Single-Dish Radio and Millimetre Telescopes (7)X-ray and Gamma-Ray Space Observatories (4)OperatorAllAssociation of Universities for Research in Astronomy (3)ASTRON (1)Astrophysical Research Consortium (1)Australian Astronomical Observatory (1)Australian National University (1)California Association for Research in Astronomy (1)California Institute of Technology (1)Carnegie Institution for Science (1)Chinese Academy of Sciences (1)CSIRO (2)DLR (1)European Southern Observatory (2)European Space Agency (3)Indian Institute of Astrophysics (2)Institut Teknologi Bandung (1)Institute of Astrophysics of Andalusia (1)Instituto de Astrofísica de Canarias (1)Massachusetts Institute of Technology (1)Max Planck Institute for Astronomy (1)Max Planck Institute for Radio Astronomy (1)Moscow State University (1)NASA (10)National Academy of Sciences of Armenia (1)National Astronomical Observatory of Japan (2)National Radio Astronomy Observatory (2)National Research Council (Canada) (2)National Research Foundation of South Africa (2)National Research Institute of Astronomy and Geophysics (1)National Science Foundation (1)New Jersey Institute of Technology (1)New Mexico State University (1)NOIRLab (1)Observatoire de Paris (1)Osmania University (1)Physical Research Laboratory (1)Russian Academy of Sciences (1)Tel Aviv University (1)University of Cambridge (1)University of Central Florida (1)University of Manchester (1)University of Texas at Austin (1)University of Toronto (1)Observing BandAllGamma-ray (1)Infrared (13)Microwave (2)Optical / Visible (38)Radio (18)Ultraviolet (3)X-ray (3)LocationAllArmenia (1)Australia (3)Australia (1)Canada (3)Chile (5)China (1)Egypt (1)France (2)Georgia (1)Germany (2)India (5)Indonesia (1)Israel (1)Japan (1)Netherlands (1)Russia (2)South Africa (2)Spain (2)Ukraine (1)United Kingdom (2)United States (15)Show ResultsBrowseCompareSelect all 64Abastumani Astrophysical Observatory20th centuryAlgonquin Radio Observatory20th centuryAnglo-Australian Telescope20th centuryApache Point Observatory20th centuryArecibo Observatory20th centuryAryabhatta Research Institute of Observational Sciences20th centuryAustralia Telescope Compact Array20th centuryBig Bear Solar Observatory20th centuryBohyunsan Optical Astronomy Observatory20th centuryBosscha Observatory20th centuryByurakan Observatory20th centuryCalar Alto Observatory20th centuryCerro Tololo Inter-American Observatory20th centuryChandra X-ray Observatory20th centuryCompton Gamma Ray Observatory20th centuryCosmic Background Explorer20th centuryCrimean Astrophysical Observatory20th centuryDavid Dunlap Observatory20th centuryDominion Astrophysical Observatory20th centuryEffelsberg 100-m Radio Telescope20th centuryExtreme Ultraviolet Explorer20th centuryFlorence and George Wise Observatory20th centuryGemini Observatory20th centuryHartebeesthoek Radio Astronomy Observatory20th centuryHaute-Provence Observatory20th centuryHaystack Observatory20th centuryHipparcos20th centuryHubble Space Telescope20th centuryInfrared Astronomical Satellite20th centuryInternational Ultraviolet Explorer20th centuryJodrell Bank Observatory20th centuryKitt Peak National Observatory20th centuryKodaikanal Solar Observatory20th centuryKottamia Astronomical Observatory20th centuryLa Silla Observatory20th centuryLas Campanas Observatory20th centuryLeibniz Institute for Astrophysics Potsdam20th centuryMauna Kea Observatories20th centuryMcDonald Observatory20th centuryMount Wilson Observatory20th centuryMullard Radio Astronomy Observatory20th centuryNancay Radio Observatory20th centuryNational Solar Observatory20th centuryNizamia Observatory20th centuryNobeyama Radio Observatory20th centuryPalomar Observatory20th centuryParkes Observatory20th centuryPurple Mountain Observatory20th centuryRoque de los Muchachos Observatory20th centuryROSAT20th centuryRossi X-ray Timing Explorer20th centurySiding Spring Observatory20th centurySolar and Heliospheric Observatory20th centurySouth African Astronomical Observatory20th centurySpecial Astrophysical Observatory20th centurySternberg Astronomical Institute20th centurySubaru Telescope20th centuryUdaipur Solar Observatory20th centuryVainu Bappu Observatory20th centuryVery Large Array20th centuryVery Large Telescope20th centuryVery Long Baseline Array20th centuryW.
