Back in 2004, the coronagraph in the High Resolution Camera on Hubble's Advanced Camera for Surveys produced the first-ever resolved visible light image of a large dust belt, similar to the Kuiper Belt in our Solar System, surrounding Fomalhaut (alpha Piscis Austrini), 25 light years distant from us. It clearly showed that this structure is in fact a ring of protoplanetary debris approximately 34.5 billion kilometres across with a sharp inner edge. At the time a few bright sources in the image were noted as possible planet candidates.
