Astronomy: What is Astronomy? History, Discoveries, Research, Analysis and Facts

Astronomy, the oldest of the natural sciences, is the study of celestial objects and phenomena that originate outside Earth's atmosphere. It involves the observation and understanding of stars, planets, comets, galaxies, and the cosmos as a whole. Unlike its sibling science, astrology, which seeks to find meaning in the movements of celestial bodies, astronomy is grounded in rigorous, observational science and aims to understand the laws governing the universe.
