Astronomy

Astronomy is the study of everything in the sky and far beyond. It looks at stars, planets, moons, and many other wonderful things in space. People have looked up at the night sky for thousands of years, wondering about the cosmos.

What Astronomers Study

Astronomers watch the sky to learn about celestial objects and what happens there. They study nebulae, galaxies, meteoroids, asteroids, and comets. These objects help us understand how the universe works. They use science, math, and special tools to see far into space.

A Very Old Science

Astronomy is one of the oldest sciences. Ancient people from places like Egypt, Babylon, Greece, India, China, and the Maya watched the night sky. They kept records of what they saw. Special places like Stonehenge and the Nebra sky disc show how people long ago were curious about the stars.

Everyone Can Help

Today, even people who are not scientists can help with astronomy. Amateur astronomers often find new things in space, like new comets, and share what they find. This makes astronomy a science where everyone can join in and help us learn more about the universe.
