. A view of the massive globular cluster NGC 1783 in the Large Magellanic Cloud, near Earth's own Milky Way, as seen by the Hubble Space Telescope. The cluster is 160,000 light-years from Earth and as massive as 170,000 Suns. ESA/Hubble NASA

... STScI-PRC99-26 HUBBLE IMAGES A SWARM OF ANCIENT STARS This stellar swarm is M80 (NGC 6093), one of the densest of the 147 known globular star clusters in the Milky Way galaxy. ... By analyzing the Wide Field and Planetary Camera 2 (WFPC2) images, including images taken through an ultraviolet filter, astronomers have found a large population of "blue stragglers" in the core of the cluster. These stars appear to be unusually young and more massive than the other stars in a globular cluster. ...
