color image combines many exposures from Hubble Space Telescope's
Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) and the
European Southern Observatory's (ESO) 2.2m telescope in La Silla, Chile.
ESO data are based on observations made with ESO Telescopes at the
La Silla Observatory in Chile under program ID 076.C-0888, processed and
released by the ESO VOS/ADP group. Observations were carried out
by J. Alves, B. Vandame, and Y. Bialetski with the Wide Field Imager
(WFI) and consist of a 2x2 WFI mosaic.
The ACS/WFC3 data are from the HST proposal 12499: D.
Lennon (ESA/STScI) et al. THe science team comprises D. Lennon and E. Sabbi (ESA/STScI), J. Anderson, S. E. de Mink, R. van der Marel, T. Sohn, and N. Walborn (STScI), N.
