What Is Astronomy?

Astronomy is the study of stars and other objects in space. Ancient peoples studied the sky and the movement of stars, the Moon, and the Sun and were able to create calendars based on their observations. These early astronomers also named individual stars and groups of stars. Since astronomers can't travel to stars and other distant objects, they use tools to study these objects. The telescope is a tool used to see deep into space. One type of telescope uses lenses to magnify faraway objects. Lenses are pieces of glass or plastic that are shaped in a way that causes them to magnify objects. Space telescopes high above Earth are also used to gather information about objects in space and send it back to astronomers. Astronomy is an exciting and rapidly changing field of study with new discoveries constantly being made.
