Caldwell 18 Inset 2

The ground-based image of Caldwell 18 (NGC 185) in the top left is from the Digitized Sky Survey (DSS) and shows the sites of some additional Hubble observations of the galaxy. The image in the upper right is a composite of observations taken by the Advanced Camera for Surveys (ACS), while the bottom two images are composites from the Wide Field and Planetary Camera 2 (WFPC2). Each Hubble image consists of observations taken in visible and infrared light.Credits: Ground-based image: Digitized Sky Survey; Hubble ACS image: NASA, ESA, and A.
