Observational Astronomy
Observational astronomy is the branch of astronomy that focuses on collecting data from celestial objects using telescopes and other instruments. It helps scientists study stars, planets, galaxies, and the universe's evolution. By analyzing light and other forms of radiation emitted by these objects, astronomers gain insights into their composition, distance, and behavior. This information is crucial for understanding fundamental concepts in astrophysics and cosmology, such as the nature of black holes, the expansion of the universe, and the formation of galaxies. Ultimately, observational astronomy bridges the gap between theoretical ideas and real-world astronomical phenomena.

Observational astronomy is the practice of studying celestial objects and phenomena by collecting and analyzing data from telescopes and other instruments. This field allows astronomers to observe stars, planets, galaxies, and more to understand their properties, movements, and the universe's structure. By using different wavelengths of light—like visible, infrared, and radio—scientists gather information that helps answer fundamental questions about the cosmos, such as how stars form, the composition of planets, and the expansion of the universe. Ultimately, observational astronomy helps us comprehend our place in the vast universe.
