An observatory is a facility or structure designed for observing celestial events and objects, such as stars, planets, and galaxies. These buildings often house powerful telescopes and other instruments that allow astronomers to study the universe in detail. Observatories can be found on Earth or in space, with each type serving different purposes and offering unique advantages. Many observatories are located in remote areas to minimize light pollution and atmospheric interference. Some well-known examples include the Hubble Space Telescope, which orbits Earth, and the Mauna Kea Observatories in Hawaii, which benefit from high altitudes and clear skies for optimal viewing conditions.
