How did Mayans use astronomy?
Maya astronomer-priests looked to the heavens for guidance. They used observatories, shadow-casting devices, and observations of the horizon to trace the complex motions of the sun, the stars and planets in order to observe, calculate and record this information in their chronicles, or “codices”.
Who created 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.
What did Egyptians think stars were?
The Egyptians referred to those stars as “the indestructibles.” Today we know them as Kochab, in the bowl of the Little Dipper (Ursa Minor), and Mizar, in the middle of the handle of the Big Dipper (Ursa Major). Early Greek astronomers learned from the Babylonians.

What is the oldest tool used astronomy?
The job of early observatories was to map the sky, so the earliest astronomical instrument was the quadrant or sextant. Using these instruments, Hipparchus at Rhodes (150 B.C.) produced the first star catalog, measured precession and developed the magnitude system of stellar brightness.
