Who Discovered the Constellations

Stars fascinate people all the time. Ancient and old civilizations have different ways of looking at stars. Some viewed stars as signs, some as other worlds. Farmers, poets, seafarers took the stars as reminders of good and bad luck. Ancient land and sea wanderers used the stars as memory aids so they would not be lost.

On the other hand, farmers read the stars to prepare for a good or bad harvest. This lead to planting and harvesting seasons. In parts of the world where different constellations appeared in different seasons, they used the stars to tell the month instead. For instance, constellation Scorpius can be seen only in northern hemisphere skies in summer.

For the record

The oldest record of star-gazing was found in Sumerian board games around 4000 BC. Sumerians named the stars after their gods. Early Chinese constellation had much in common with Middle Eastern and Western constellation.  The Babylonians had divided the zodiac into 12 signs by 450 BC. The present constellation is largely based on Egyptian astrology. The Greeks named 48 constellations.

Constellation controversy

By the end of the 16th Century European seafarers drew maps of the austral hemisphere.  Pieter Dirckz Keyser added a few more constellations while on board a ship to the East Indies in 1595.   His version was added to Johann Bayer’s, a German cartographer who published an atlas of Europe. More European experts offered new constellations such as the French Nicolas Louis. The International Astronomy Union fixed the number of constellations to 88.

The 12 constellations on the ecliptic side were called as the Zodiacs. Twenty-nine constellations lie between the North Celestial Pole and the ecliptic. The constellation Ophiuchus is part of the ecliptic side. The remaining 47 constellations are found between the South Celestial Pole and the ecliptic side.

Constellations today

Many of the old constellations have been changed. Their positions have been fixed in the sky. Of the 88 constellations, three animals appear twice: Pisces/Pisces Austrinus, Ursa Major/Ursa Minor,  and Canis Major/Canis Minor. The northern hemisphere constellations have not changed for the last 2000 years.
