  The search for exoplanets has encompassed a broad range of stellar
environments, from single stars in the solar neighborhood to multiple stars and
various open clusters. The stellar environment has a profound effect on planet
formation and stability evolution and is thus a key component of exoplanetary
studies. Dense stellar environments, such as those found in globular clusters,
provide particularly strong constraints on sustainability of habitable
planetary conditions. Here, we use Hubble Space Telescope observations of the
core of the Omega Centauri cluster to derive fundamental parameters for the
core stars. These parameters are used to calculate the extent of the Habitable
Zone of the observed stars. We describe the distribution of Habitable Zones in
the cluster and compare them with the stellar density and expected stellar
encounter rate and cluster dynamics. We thus determine the effect of the
stellar environment within the Omega Centauri core on the habitability of
planets that reside within the cluster. Our results show that the distribution
of Habitable Zone outer boundaries generally lie within 0.5 AU of the host
stars, but that this small cross-sectional area is counter-balanced by a
relatively high rate of stellar close encounters that would disrupt planetary
orbits within the Habitable Zone of typical Omega Centauri stars.
