Observational astronomy is a branch of astronomy that involves the direct observation and study of objects in the universe using telescopes and other instruments. It focuses on collecting data, such as images, spectra, and light curves, to understand the properties and behavior of celestial objects such as stars, planets, galaxies, and other astronomical phenomena. Observational astronomers often use telescopes located on the ground or in space to conduct their research and make important discoveries about the universe. This field is essential for advancing our understanding of the cosmos and plays a crucial role in the scientific study of the universe.
