What is Astronomy?

Astronomy is a natural science that deals with the study of celestial objects (such as moons, planets, stars, nebulae and galaxies); the physics, chemistry, and evolution of such objects; and phenomena that originate outside the atmosphere of earth (such as supernova, gamma ray bursts, and cosmic background radiation). A related but distinct subject, cosmology, is concerned with studying the universe as a whole.
