Astronomy

Definition of Astronomy as it relates to Science

Astronomy is the scientific study of celestial objects and phenomena outside Earth's atmosphere. It involves observing stars, planets, galaxies, and other cosmic entities through telescopes, spacecraft, and other scientific instruments to understand their physical properties, chemical composition, structure, and evolution. Astronomers use principles of physics, mathematics, and chemistry to analyze data and develop theories about the universe's origins, its current state, and its eventual fate. The field encompasses various sub-disciplines such as astrophysics, planetary science, stellar evolution, and cosmology. Astronomy has played a vital role in shaping humanity's understanding of the cosmos and our place within it.
