Astrophysical observatories are specialized facilities designed to study celestial objects and phenomena in the universe. They use various instruments, such as telescopes and detectors, to observe light and other forms of radiation emitted by stars, planets, and galaxies. These observatories can be located on Earth or in space, allowing scientists to gather data from different wavelengths, including visible light, infrared, and radio waves. Many observatories are equipped with advanced technology to enhance their observational capabilities. Notable examples include the Hubble Space Telescope, which orbits Earth, and the Keck Observatory in Hawaii. These facilities contribute significantly to our understanding of the universe, helping astronomers explore topics like the formation of stars, the behavior of black holes, and the expansion of the universe.
