HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT      #4757 PERIOD COVERED: 5am December 15 - 5am December 16, 2008 (DOY 350/1000z-351/1000z) OBSERVATIONS SCHEDULED FGS 11704 The Ages of Globular Clusters and the Population II Distance Scale Globular clusters are the oldest objects in the universe whose age can be accurately determined. The dominant error in globular cluster age determinations is the uncertain Population II distance scale. We propose to use FG ...Continue Reading
