Near the center of the image is a bright orange star, and in the upper left, are two reddish-pink stars near each other. The entire image is filled by a turquoise, cloud-like "bubble".

C56 (NGC 246)

This image of the planetary nebula Caldwell 56 was captured by Hubble’s Wide Field and Planetary Camera 2. It provides a detailed look at the structure of C56 and its central star. These observations, and subsequent ones, were taken to better understand how the wispy filaments in planetary nebulae change over time.
