What is Astronomy?

Astronomy is an ancient science that seeks to understand the universe and its origins. It studies the behavior of stars, planets, galaxies, asteroids, comets and other celestial objects. Astronomers use a variety of tools such as telescopes, radio telescopes and satellites to observe astronomical phenomena from Earth or space. Through their observations, astronomers have been able to uncover some of the mysteries surrounding our universe. Astronomy has had many profound effects on humanity throughout history. Ancient civilizations used astronomy for purposes ranging from navigation at sea to predicting seasonal changes in crop production. Modern-day astronomy has enabled us to gain insight into previously unknown areas such as dark matter and black holes; it has also provided us with invaluable data about our own planet Earth through satellite imagery taken from space. Not only this but it has helped us answer questions about how we got here such as where did all the elements come from that make up our world? How did life begin? What are the chances of finding another inhabited planet out there? Today’s professional astronomers work in various fields including astrophysics, cosmology, astrobiology and planetary science; they continue to explore new ways to study our ever-changing universe and learn more about its inner workings. Amateur astronomers worldwide take part in activities like skywatching with binoculars or telescopes many even capture images using specialized equipment or become citizen scientists by contributing data collected from their backyard observatories to scientific projects around the globe. Finally, educational programs that offer students hands-on experience with astronomy help open minds towards understanding more about what lies above them in our vast night sky.
