DEBRIS RING AROUND A STAR: ANNOTATED
This view points out important features in the image, such as the ring's inner and outer edges. Astronomers used the Advanced Camera for Surveys (ACS) coronagraph aboard Hubble to block out the light from the bright star so they could see the faint ring. Despite the coronagraph, some light from the star is still visible in this image, as can be seen in the wagon wheel-like spokes that form an inner ring around Fomalhaut [labeled 'scattered light 'noise''].
