HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4223 PERIOD COVERED: UT October 19, 2006 (DOY 292) OBSERVATIONS SCHEDULED ACS/WFC 10816 The Formation History of Andromeda's Extended Metal-Poor Halo We propose deep ACS imaging in the outer spheroid of the Andromeda galaxy, in order to measure the star formation history of its true halo. For the past 20 years, nearly all studies of the Andromeda "halo" were focused on the spheroid within 30 ...Continue Reading
