Globulars Star Clusters of the Milky Way

Here we journey to the Milky Way's globular clusters—all 157 of them.  Some of these globulars, as you will see in the image links below, are barely detectable, if at all, because of obscuring dust and gas (and even dense forests of foreground stars).  Others are very small, probably because they are very far away and obscured by foreground material.  Still others look remarkably like many of the NGC globulars; this is particularly true in the deep southern hemisphere of the sky which even at the time of the NGC was still relatively neglected.  Not included in this list are several suspected globulars because they have not yet been confirmed.  Some of these have properties reminiscent of both globular and galactic star clusters, so we are not quite sure yet what we are looking at.

47 of the 88 constellations (53%) contain globular clusters.  Adjacent constellations Ophiuchus and Sagittarius, which are tied for having both the most Messier and the most Messier+NGC globulars, are not equal when we consider all the Milky Way's globular clusters.  Sagittarius emerges as the clear winner with 35.   Ophiuchus has 25, and Scorpius 19.  These three adjacent constellations combined harbor half of all the globular clusters in the sky!  Perhaps this is not too surprising considering that the center of our Milky Way galaxy is located 27,000 light years from here in Sagittarius near the Sagittarius-Ophiuchus-Scorpius border.

Here is an object-by-object tour of all the Milky Way's globular clusters, grouped by constellation.  The constellation charts are courtesy of the International Astronomical Union in collaboration with Roger Sinnott, Rick Fienberg, Alan MacRobert, and Sky & Telescope magazine.  The photographic atlas of these extraordinary objects has been provided by wikisky.org.  The Sagittarius-Ophiuchus-Scorpius map linked above was created with Voyager 4.5.5 for Mac OS X, from Carina Software & Instruments.
