optical telescopy

Optical astronomy involves using telescopes to observe distant objects in space by capturing visible light. These telescopes gather and focus light from stars, planets, and galaxies, allowing astronomers to study their properties, such as structure, composition, and motion. The main types include refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors. Advanced designs and technology, like large mirror surfaces and digital sensors, improve image clarity and detail. Optical telescopes are essential tools for exploring the universe, helping us understand the origins, evolution, and nature of celestial objects.
