astronomical instruments

Astronomical instruments are devices used to observe and analyze celestial objects and phenomena beyond Earth. Telescopes gather and focus light from stars, planets, and galaxies, enabling detailed viewing and measurement. Cameras and spectrometers attached to telescopes capture images and analyze the light’s properties to determine composition, temperature, and motion. Other tools, like detectors and filters, help scientists study specific wavelengths or faint objects. These instruments are essential for expanding our understanding of the universe, allowing us to see distant objects, study their behavior, and gain insights into the cosmos's origin and evolution.
