An astronomer or astrophysicist is a person whose area of interest is astronomy or astrophysics.
Interest in the sky
Cultures around the world appear to have taken an interest in the sky since prehistoric times. Independently, some of these cultures began to support groups of scribes or priests who dedicated themselves to the observation of objects in the heavens. The observation of the motions of the planets, and prediction of their future motions, was the chief occupation of ancient astronomy. In the west, astronomy is generally thought to have begun in ancient Mesopotamia. Recent studies of Babylonian records have shown them to be extremely accurate for the ancient night sky.
Astrology background
It is important to recognize that before about 1750, astrology was considered to be a science closely allied to astronomy. In some times and places, the two have been regarded as identical. More on [ Astronomer ]
