Lesson 1: What is Astronomy?

Astronomy is the scientific study of celestial objects, space, and the entire universe. It explores planets, stars, galaxies, and phenomena beyond Earth's atmosphere, seeking to understand their behavior, origins, and evolution. Unlike astrology, which is based on belief, astronomy relies on observation and scientific principles to uncover the laws of physics that govern the cosmos. Through telescopes and space missions, astronomers unravel the mysteries of the vast, ever-expanding universe.
