Glossary term: Astronomy

Description: Astronomy is one of the ancient sciences and involves the study of celestial bodies in the sky such as stars, planets, galaxies, meteors, and meteorites. It also studies the atmosphere for the purposes of comparing planet Earth with neighboring planets. In the past, astronomy was concerned with tracking the positions of the Sun, Moon, and planets for calendar and navigational purposes. Modern astronomers now also study the physical phenomena that govern the formation and behaviour of astronomical objects. In ancient times astronomy was often closely related to the pseudoscience astrology and many people still do not know the difference between the two. Astronomy is one of the few sciences in which amateurs can play an important role, as amateur astronomers have contributed to many important discoveries.
