in Lithuania]] An observatory is a location used for observing terrestrial and/or celestial events. Astrology , Astronomy , Climatology / Meteorology , Geology , Oceanography and Volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing a Sextant (for measuring the distance between Star s) or Stonehenge (which has some alignments on astronomical phenomena). ASTRONOMICAL OBSERVATORIES Ground-based observatories , home of the Very Large Telescope , a cluster of four large (8.2 meter diameter) telescopes.]] Ground-based observatories, located on the surface of Earth, are used to make observations in the Radio and Visible Light portions of the Electromagnetic Spectrum . Most Optical Telescope s are housed within a Dome or other similar structure in order to protect the delicate instruments from the elements. Telescope domes contain a slat or other opening in the roof that can be opened during observing and then closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated in order to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes. Optical observatories |
