C40 Image Comparison
A ground-based image of Caldwell 40 (NGC 3626) from the Digitized Sky Survey (DSS) appears in the upper left. A yellow rectangle in that image shows the area imaged by Hubble’s Wide Field Camera 3 (WFC3) in infrared (IR) light on the right. A blue rectangle in the WFC3 IR image shows the field covered by the WFC3 image in the lower left, which combines observations taken in ultraviolet, visible, and infrared light.
