=== Space-based observatories ===
|
||
|
||
Space-based observatories are telescopes or other instruments that are located in outer space, many in orbit around the Earth. Space telescopes can be used to observe astronomical objects at wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere and are thus impossible to observe using ground-based telescopes. The Earth's atmosphere is opaque to ultraviolet radiation, X-rays, and gamma rays and is partially opaque to infrared radiation so observations in these portions of the electromagnetic spectrum are best carried out from a location above Earth's atmosphere. Another advantage of space-based telescopes is that, because of their location above the Earth's atmosphere, their images are free from the effects of atmospheric turbulence that plague ground-based observations. As a result, the angular resolution of space telescopes such as the Hubble Space Telescope is often much smaller than a ground-based telescope with a similar aperture. However, all these advantages do come with a price. Space telescopes are much more expensive to build than ground-based telescopes. Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope was able to be serviced by the Space Shuttles while many other space telescopes cannot be serviced.

|
||
=== Airborne observatories ===
|
||
|
||
Airborne observatories have the advantage of height over ground installations, putting them above most of the Earth's atmosphere. They also have an advantage over space telescopes: The instruments can be deployed, repaired and updated much more quickly and inexpensively. The Kuiper Airborne Observatory and the Stratospheric Observatory for Infrared Astronomy use airplanes to observe in the infrared, which is absorbed by water vapor in the atmosphere. High-altitude balloons for X-ray astronomy have been used in a variety of countries.

|
||
=== Neutrino observatories ===

||
|
||
Example underground, underwater or under ice neutrino observatories include:
|
||
|
||
1998–2003 Gallium Neutrino Observatory
|
||
1999–2006 Sudbury Neutrino Observatory
|
||
2003 Baikal Deep Underwater Neutrino Telescope

== Marine observatories ==
|
||
A marine observatory is a scientific institution whose main task is to make observations in the fields of meteorology, geomagnetism and tides that are important for the navy and civil shipping. An astronomical observatory is usually also attached. Some of these observatories also deal with nautical weather forecasts and storm warnings, astronomical time services, nautical calendars and seismology.
|
||
Example marine observatories include:
|
||
|
||
1676 Royal Greenwich Observatory at London
|
||
1753 Real Instituto y Observatorio de la Armada in San Fernando, Spain
|
||
1830 United States Naval Observatory
|
||
1868 German Maritime Observatory in Hamburg
|
||
1871–1918 Austro-Hungarian Pola Naval Observatory, in what is now Pula, Croatia
|
||

== Magnetic observatories ==
|
||
A magnetic observatory is a facility which precisely measures the total intensity of Earth's magnetic field for field strength and direction at standard intervals. Geomagnetic observatories are most useful when located away from human activities to avoid disturbances of anthropogenic origin, and the observation data is collected at a fixed location continuously for decades. Magnetic observations are aggregated, processed, quality checked and made public through data centers such as INTERMAGNET.
|
||
The types of measuring equipment at an observatory may include magnetometers (torsion, declination-inclination fluxgate, proton precession, Overhauser-effect), variometer (3-component vector, total-field scalar), dip circle, inclinometer, earth inductor, theodolite, self-recording magnetograph, magnetic declinometer, azimuth compass. Once a week at the absolute reference point calibration measurements are performed.
|

||
1833 Göttingen Observatory, Germany
|
||
1840 Toronto Magnetic and Meteorological Observatory, Canada
