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.Facts21st centurySourcesComments (0)Reader Challenges (0)FactsComparisonField Origin EraWell-attested1608 121st centuryFilter Results34 entriesPlatformAllCosmic Microwave Background Satellites (2)Infrared Space Telescopes (7)Optical Observatories of Africa and Oceania (1)Optical Observatories of Europe (1)Optical Observatories of the Americas (3)Optical, Ultraviolet and Exoplanet Space Telescopes (2)Radio and Millimetre Interferometer Arrays (6)Single-Dish Radio and Millimetre Telescopes (4)Solar Space Observatories (1)X-ray and Gamma-Ray Space Observatories (4)OperatorAllAssociation of Universities for Research in Astronomy (1)ASTRON (1)CSIRO (1)European Southern Observatory (1)European Space Agency (6)Green Bank Observatory (1)ISRO (1)JAXA (1)Large Binocular Telescope Corporation (1)NASA (13)National Radio Astronomy Observatory (1)National Science Foundation (1)NOIRLab (1)Roscosmos (1)SLAC National Accelerator Laboratory (1)South African Astronomical Observatory (1)Swiss Space Office (1)University of Chicago (1)University of Toronto (1)Observing BandAllGamma-ray (3)Infrared (7)Microwave (4)Optical / Visible (11)Radio (8)Ultraviolet (2)X-ray (2)LocationAllAntarctica (1)Australia (1)Canada (1)Chile (3)China (1)Netherlands (1)South Africa (2)Spain (1)United States (3)Show ResultsBrowseCompareSelect all 34Akari21st centuryAstroSat21st centuryAtacama Cosmology Telescope21st centuryAtacama Large Millimeter Array21st centuryAustralian Square Kilometre Array Pathfinder21st centuryCanadian Hydrogen Intensity Mapping Experiment21st centuryCHEOPS21st centuryDaniel K.
