... Credit Copyright: Damian Peach Explanation: Some 13,000 light-years away toward the southern constellation Pavo, the globular star cluster NGC 6752 roams the halo of our Milky Way galaxy. ... Telescopic explorations of the NGC 6752 have found that a remarkable fraction of the stars near the cluster's core, are multiple star systems. ...

home publications > mercury . ... Big Clusters, Tiny Galaxies . ... Astronomers struggle to understand why giant star clusters form in the tiniest of galaxies . ... These clusters are probably young versions of globular clusters, but they are commonly called super star clusters. Seven dwarf galaxies within 16 million light-years have formed super star clusters, with one of these galaxies, NGC 1569, possessing two young clusters. ... Super star clusters have a lot to tell us about star formation. ...

... 2003 December 15 . Open Star Clusters M35 and NGC 2158 . ... NGC 2158 is four times more distant that M35 , over 10 times older, and much more compact as it contains many more stars in roughly the same volume of space. NGC 2158 's bright blue stars have self-destructed , leaving cluster light to be dominated by older and yellower star s. Both clusters are visible toward the constellation of Gemini -- M35 with binoculars and NGC 2158 with a small telescope. ... About APOD | ...

NGC 5986, a little-studied southern-hemisphere globular cluster, is remarkable in containing two very luminous A-F type stars, discovered by me in the 1970's. These objects are probably in their final evolution off the asymptotic giant branch. ... Determining the distance to NGC 5986 will help calibrate the absolute brightnesses of post-AGB A-F stars. ... NGC 5986: last updated 2001 December 20 . Mike Siegel and I have found a post-AGB star in the globular cluster M79 (NGC 1904). ...

... October 18, 1999 . NGC 3603: An Active Star Cluster . ... Explanation: NGC 3603 is home to a massive star cluster, thick dust pillars, and a star about to explode . The central open cluster contains about 2000 bright stars, each of which is much brighter and more massive than our Sun . ... These stars are less massive than our Sun, demonstrating that great numbers of low-mass stars also form in active starburst regions . ... About APOD > . ...

An eight-billion-year-old cluster of stars 13,000 light-years from Earth, called NGC 6791, can be seen in the image. ... This particular cluster is called an open cluster, because the stars are loosely bound and have started to spread out from each other. The area pictured is 0.2 percent of Kepler's full field of view, and shows hundreds of stars in the constellation Lyra. The image has been color-coded so that brighter stars appear white, and fainter stars, red. ...

... BLUE STRAGGLER STARS are unusually hot and bright stars found in the cores of ancient star clusters known as globulars. ... BACKGROUND (from wikipedia): Blue straggler stars are stars in open or globular clusters that are hotter and bluer than other cluster stars having the same luminosity. ... There is evidence in favor of this view, notably that blue straggler stars appear to be much more common in dense regions of clusters, especially in the cores of globular clusters. ...

Swarms of tightly packed stars, numbering in the thousands to low millions, globular clusters are cosmic fossils, relics of the early times of our galaxy. Omega Centauri may actually be the core of a smaller galaxy ripped apart and assimilated by our own Milky Way in the distant past. ...
