SUMMARY:The Small Magellanic Cloud Star Formation History\, Special As
 tronomy Colloquium at Noon\, Elena Sabbi\, STSci
DESCRIPTION:The Small Magellanic Cloud (SMC) is a unique laboratory to
  study a wide range of astrophysical phenomena\, from the birth and ev
 olution of stars\, through the physics of the multi-phase interstellar
  medium\, to the dynamics and evolution of galaxies. At only 60 kpc fr
 om us\, the SMC is the closest late-type dwarf galaxy with active star
  formation. With a present-day metal abundance about a factor eight lo
 wer than that of the Sun\, the SMC allows to investigate the star form
 ation processes in an environment typical of the formation of the type
 s of galaxies that dominate the appearance of today's Universe. Hence 
 the SMC is an important template for understanding the evolution of ga
 laxies as an astrophysical system.<br><br>
\n<br><br>
\nThe properties
  of the SMC encouraged us to start a deep imaging survey using the exq
 uisite capabilities of the Advanced Camera for Surveys (ACS) on board 
 of the Hubble Space Telescope (HST) with the objective of investigate 
 the properties of its stellar populations in the bar\, the wing and th
 e bridge\, in the field as well as in intermediate and old star cluste
 rs and in HII star forming regions.<br><br>
\n<br><br>
\nI will discus
 s the age-metallicity relation\, the three dimensional structure of th
 e SMC halo\, the impact of local and global conditions on star formati
 on\, and the star formation history of this galaxy over the entire Hub
 ble time\, in the context of late-type dwarf galaxy evolution.
