Observational Astronomy

Observational astronomy, a core branch of astronomy, focuses on gathering data about celestial objects. Unlike theoretical astronomy, it relies on direct observation using telescopes and other instruments across the electromagnetic spectrum. This involves meticulous data collection, analysis, and interpretation to understand the universe's composition, structure, and evolution. Techniques range from visual observation to sophisticated digital imaging and spectroscopy. The field fuels discoveries about stars, galaxies, planets, and more, providing the empirical foundation for astronomical theories.
