Astronomy

Exploring planets, stars, and galaxies — and helping you understand the universe above Harford County and beyond.

Astronomy is the scientific study of the universe beyond Earth. From the planets in our solar system to distant galaxies billions of light-years away, astronomy helps us understand how the universe formed, how it works, and our place within it.

For thousands of years people have looked up at the night sky and wondered about the stars. Today astronomers use powerful telescopes, spacecraft, and satellites to study objects that are unimaginably far away. Yet astronomy is still one of the most accessible sciences—anyone can step outside on a clear night and observe the sky.

On this page you will find resources exploring the solar system, stars, galaxies, and the tools astronomers use to study space. Whether you’re just starting to learn about astronomy or looking to deepen your understanding, the universe offers endless opportunities for discovery.
