Bright clusters of stars form and disperse near the center of our Galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap970121.html ]. Four million years ago the Quintuplet Cluster, pictured above [ http://oposite.stsci.edu/pubinfo/pr/1999/30/index.html ], formed and is now slowly dispersing. The Quintuplet Cluster is located within 100 light-years [ http://chandra.harvard.edu/photo/cosmic_distance.html ] of the Galactic center [ http://antwrp.gsfc.nasa.gov/apod/ap990911.html ], and is home to the brightest star yet cataloged in our Galaxy: the Pistol Star [ http://antwrp.gsfc.nasa.gov/apod/ap971008.html ]. Objects near our Galactic center [ http://antwrp.gsfc.nasa.gov/apod/ap990621.html ] are usually hidden from view by opaque dust [ http://antwrp.gsfc.nasa.gov/apod/ap990509.html ]. This recently-released picture [ http://oposite.stsci.edu/pubinfo/pr/1999/30/pr.html ] was able to capture the cluster in infrared light [ http://www.us-gemini.noao.edu/public/infrared.html ], though, with the NICMOS [ http://www.stsci.edu/hst/#nicmos ] camera onboard the orbiting Hubble Space Telescope [ http://www.stsci.edu/hst/ ]. The young Quintuplet Cluster [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1999ApJ...514..202F ] is one of the most massive open clusters [ http://antwrp.gsfc.nasa.gov/apod/ap970128.html ] yet discovered, but still much less massive than the ancient globular clusters [ http://antwrp.gsfc.nasa.gov/apod/ap981107.html ] that orbit in the distant halo. Some of the bright white stars visible above may be on the verge [ http://antwrp.gsfc.nasa.gov/apod/ap980816.html ] of blowing themselves up in a spectacular supernova [ http://antwrp.gsfc.nasa.gov/apod/ap981230.html ].
