Open clusters are very different from globular clusters. .
As the Milky Way runs through Puppis,there are a large number of open clusters in the constellation.
Open clusters are also easily detected in many of the galaxies of the Local Group.
Numbers and distribution==There are over 1,000 known open clusters in our galaxy, but the true total may be up to ten times higher than that.
Open clusters have been found only in spiral and irregular galaxies, in which active star formation is occurring.
NGC 1872 has characteristics of both globular clusters and open clusters- it is visually as rich as a typical globular butis much younger, and, like many open clusters, has bluer stars.
Open clusters generally survive for a few hundred million years, with the most massive ones surviving for a few billion years.
Influenced by Galileo's work, the Sicilian astronomer Giovanni Hodierna became possibly the first astronomer touse a telescope to find previously undiscovered open clusters.

More than 1,100 open clusters have been discovered within the Milky Way Galaxy, and many more are thought to exist.
Young open clusters may still be contained within the molecular cloud from which they formed, illuminating it to create an H II region.
In irregular galaxies, open clusters may be found throughout the galaxy, although their concentration is highest where the gas density is highest.
Because of their location, open clusters are occasionally referred to as galactic clusters, a term that was introduced in 1925 by the Swiss-American astronomer Robert Julius Trumpler.
