Description:
Using the Advanced Camera for Surveys on the Hubble Space Telescope, Thomas Brown
(STScI) et al. obtained deep optical images reaching well below the oldest main
sequence turnoff in six fields of the Andromeda Galaxy. The fields fall at four
positions on the southeast minor axis, one position in the giant stellar stream,
and one position on the northeast major axis. These data were obtained as part of
three large observing programs (9453, 10265, 10816) designed to probe the star
formation history of the stellar population in various structures of the galaxy.
The Galaxy Evolution Explorer (GALEX), a NASA Small Explorer mission, is performing the first all-sky, deep imaging and spectroscopic ultraviolet surveys in space. The prime goal of GALEX is to study star formation in galaxies and its evolution with time.
