Astronomical Instruments
Astronomical instruments are devices used to observe and measure celestial objects and phenomena. These instruments include telescopes, spectrographs, photometers, and radiometers. Telescopes are the most common astronomical instrument and are used to collect and focus light from distant objects. Spectrographs are used to analyze the light collected by telescopes, breaking it down into its component colors to determine the chemical composition and other properties of celestial objects. Photometers measure the intensity of light emitted by celestial objects, while radiometers measure the amount of radiation emitted by these objects. Astronomical instruments are used by astronomers to study the universe and to make observations that can help us better understand the nature of the cosmos.
