Ancient astronomers and their contributions
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy .
Ancient astronomers and their contributions
The nearest stars to Earth are three stars that lie about 4.37 light-years away in the Alpha Centauri triple-star system.
The closest of these stars, Proxima Centauri, is just about 4.24 light-years away. (for reference, one light-year is approximately equivalent to 5.88 trillion miles (9.46 trillion kilometers))..

Early astronomers
They have looked at the movement of the stars and the changes of the Sun and Moon.
Using what was known about the positions of stars, eclipses, and Moon phases star maps were made.
This information was used to make calendars and measure time.
It was very useful for planning when to plant crops, or for finding your way..
Early astronomers
Tycho Brahe (1580's) was astronomy's 1st true observer.
He built the Danish Observatory (using sextant's since telescopes had not been invented yet) from which he measured positions of planets and stars to the highest degree of accuracy for that time period (1st modern database)..
How far are stars in the past?
All of the stars you can see with the unaided eye lie within about 4,000 light-years of us.
So, at most, you are seeing stars as they appeared 4,000 years ago..
How far into the past can we see?
And, luckily, we can get hints about this by looking even farther back than Hubble or Webb can manage.
We can see light from 13.8 billion years ago, although it is not starlight, because there were no stars then.
The farthest light we can see is the cosmic microwave background..
Is astronomy older than physics?
Initially a cosmic curiosity, the night sky was eventually decoded by ancient peoples, making astronomy one of (if not the) oldest science.

What is the oldest branch of astronomy?
Astrometry: This ancient branch of astronomy concerns precise calculations of the motions of the sun, the moon and the planets.
It includes predictions of solar and lunar eclipses and meteor showers..

Who is ancient astronomy?
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level.
The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus..
