Astronomical observatories are facilities equipped with telescopes and other instruments for observing celestial objects and phenomena. These observatories are used by astronomers to study stars, planets, galaxies, and other astronomical objects, as well as to conduct research on topics such as the origins of the universe, the evolution of stars, and the search for extraterrestrial life. Astronomical observatories can be located on the ground or in space, and are often used in conjunction with other instruments such as radio telescopes, infrared telescopes, and X-ray telescopes to gather data from a wide range of wavelengths. Many observatories are operated by universities, research institutions, and government agencies, and are essential for advancing our understanding of the universe.
