HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4153 PERIOD COVERED: UT July 11, 2006 (DOY 192) OBSERVATIONS SCHEDULED ACS/HRC 10512 Search for Binaries Among Faint Jupiter Trojan Asteroids We propose an ambitious SNAPSHOT program to survey faint Jupiter Trojan asteroids for binary companions. We target 150 objects, with the expectation of acquiring data on about 50%. These objects span Vmag = 17.5-19.5, a range inaccessible with ground-based adaptive optics. We now have a signifi ...Continue Reading

In the past 3 years we have discovered a population of much more rare and much larger {500-2000+ km} icy planetoids in the Kuiper belt. These objects are the larges ...Continue Reading

These observations will be used to verify the accuracy of the flats currently in the pipeline and to monitor any changes. Weekly coronagraphic monitoring is required to assess the changing position of the spots. ACS/HRC 10752 Cycle 14 Focus Monitor The focus ...Continue Reading

We will use FGS1r TRANS mode observations to search for astrometric companions in the separation range of 0.01 to 1.00 arcsec and in the magnitud ...Continue Reading

This result lends credence to the collapsar model, where a rotating massive star ends its life leaving a black hole or a highly magnetized neutron star, and confirms its essential aspects. The focus of attention now ...Continue Reading
