The image on the right is a portion of the first image returned by the Wide Field/Planetary Camera on the Hubble Space Telescope (HST). On the left is a ground based image of the same area of the sky. The object shown in these images is a double star: the pair of stars is well separated in the HST image but blurred together in the ground based image.
