On the left is a ground-based image from a telescope at the European Southern Observatory (ESO), showing clouds of reddish gas and dark dust with a bright but indistinct haze of stars at their center. On the right is Hubble's image of several bright whitish stars surrounded to dimmer red stars.

This image provides context for Hubble’s observation of Caldwell 82 (NGC 6193). The image on the left is a ground-based image from a telescope at the European Southern Observatory (ESO) in Chile, and the image on the right is from Hubble’s Advanced Camera for Surveys (ACS). Energy from the two bright, O-type stars at the heart of the cluster are shaping the nearby clouds of dust and gas in the surrounding nebula, known as NGC 6188.
