Observational Astronomy

Observational astronomy involves studying celestial objects and phenomena through direct observation. By using telescopes and other instruments, astronomers analyze the light and other signals emitted by stars, planets, and galaxies. This branch of astronomy helps us understand the universe's structure, origins, and evolution. Observational techniques include photometry, spectroscopy, and astrometry, each offering insights into different aspects of cosmic objects and their behavior.
