astronomical instrument

An astronomical instrument is a device used by astronomers to observe and analyze celestial objects like stars, planets, and galaxies. These instruments include telescopes, spectrometers, and cameras that gather light or other signals from space. By collecting and magnifying faint light or analyzing its properties, they help scientists understand the universe's structure, composition, and behavior. Different instruments are designed for specific tasks, such as taking detailed images, measuring spectra, or detecting phenomena beyond visible light. Overall, they are essential tools that extend our senses, allowing us to study the cosmos from Earth or space-based platforms.
