Abstract:The Advanced Camera for Surveys and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) have been used to obtain new Hubble Space Telescope images of NGC 4038/4039 ("The Antennae"). These new observations allow us to better differentiate compact star clusters from individual stars, based on both size and color.

Observations of the main bodies of NGC 4038/39 were made with the
Hubble Space Telescope (HST), using the ACS, as part of Program
GO-10188. Multi-band photometry was obtained in the following optical
broadband filters: F435W (~B), F550M (~V), and F814W (~I).
Archival F336W photometry of the Antennae (Program GO-5962) was used
to supplement our optical ACS/WFC observations.
Infrared observations were made using the Near Infrared Camera and
Multi-Object Spectrometer (NICMOS) camera on HST as part of Program
GO-10188. Observations were made using the NIC2 camera with the F160W,
F187N, and F237M filters, and the NIC3 camera with the F110W, F160W,
F164W, F187N, and F222M filters.
