Overview
Today there are eighty-eight constellations but this has not always been so. Most of the constellations known to us today have been around since ancient times and many have been added since.
Argo Navis is the only constellation from Ptolemy's list of 48 constellations that is not included in today's list of 88 compiled by the International Astronomical Union!
When European explorers sailed beyond the equator a whole new sky was opened up to them, new constellations were added and the size of known universe doubled.
Constellations are supposed to be used as a guide to the night sky, yet some of them became so large and unwieldy they were split into smaller constellations. Others so small and insignificant they were combined into larger constellations.
