History of Constellations

The constellations that we know today have been around for many thousands of years. The ancient Greeks and Babylonians both recognized different constellations and recorded their observations in star charts. In addition to the Greeks and Babylonians, the Egyptians and other cultures around the world have also made contributions to our understanding of the night sky.

There are 88 constellations in the night sky today, divided between the northern and southern hemispheres. This number has not always been the same, however. The ancient Greeks recognized 48 different constellations in the night sky, while the Romans added 14 more. The number of constellations has grown over the centuries, as astronomers have slowly identified new stars in the night sky.
