Modern Constellations
The Ptolemaic constellations can be found in modern times although many boundary alterations have occurred and some names have been revised. Since the days of the ancient Greeks many new constellations have been proposed and rejected; this list is fairly extensive. It was determined that some authority was required to standardize this effort.
In 1919, the International Astronomical Union (IAU) was formed to govern, promote & safeguard the science of astronomy. By 1930 the IAU had divided the sky into eighty-eight official constellations, each with specified boundaries. This is the system in use today.
