Early astronomers
Ancient people, like people today, cared about astronomy because they believed the motions of celestial bodies predicted, in part or in full, future events and the behaviors of people..
Early astronomers
Ancient peoples first looked up thousands of years ago, and the stars were there; pinpoints of light that seemed to slowly rotate around the Earth.
The first astronomers also noticed the planets, the Moon and the Sun, and their motions across the night sky..

And that's why many historians consider astronomy to be the oldest science..
Early astronomers
Throughout history civilizations have developed unique systems for ordering and understanding the heavens.
Babylonian and Egyptian astronomers developed systems that became the basis for Greek astronomy, while societies in the Americas, China and India developed their own..

Types of astronomy
In the past century or so, astronomy has been broadly split into two camps — observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work)..
When was astronomy first discovered?
One of the earliest recorded astronomical observations is the Nebra sky disk from northern Europe dating approximately 1,600 BC.
This 30 cm bronze disk depicts the Sun, a lunar crescent and stars (including the Pleiades star cluster)..
Where did the term astronomy originate?
Astronomy (from the Greek ἀστρονομία from ἄστρον astron, "star" and -νομία -nomia from νόμος nomos, "law" or "culture") means "law of the stars" (or "culture of the stars" depending on the translation)..
Who was the first scientist to study astronomy?
Galileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries.
He is often referred to as the “father of modern astronomy” and the “father of modern physics”..
