Two images of Caldwell 1. Lower left is a wide-field image that shows the location of the Hubble image. Right two-thirds is the Hubble image, which shows a scattering of stars against a black backdrop.

Hubble Caldwell 1

An image in the lower left, taken with the 0.9-meter telescope at Arizona’s Kitt Peak National Observatory, provides a full view of star cluster Caldwell 1 (NGC 188). The inset shows Hubble’s Wide Field Camera 3 (WFC3) close-up image of stars near the center of the cluster.
