CCD-based Astronomy
CCD-based astronomy uses charge-coupled devices (CCDs)—specialized electronic sensors—to capture images of celestial objects. When light from stars, planets, or galaxies hits the CCD, it generates electrical signals proportionate to the brightness and color of the light. These signals are then processed to produce detailed, high-resolution digital images. CCDs are highly sensitive, allowing astronomers to observe faint objects and gather precise data vital for research. Their efficiency, stability, and ability to digitalize signals revolutionized astronomy, enabling modern exploration and analysis of the universe with clarity and accuracy.
