      Explanation: Astronomers turn detectives when trying to figure out the   
      cause of startling sights like NGC 1316. Investigations indicate that   
      NGC 1316 is an enormous elliptical galaxy that started, about 100   
      million years ago, to devour a smaller spiral galaxy neighbor, NGC   
      1317, just on the upper right. Supporting evidence includes the dark   
      dust lanes characteristic of a spiral galaxy, and faint swirls and   
      shells of stars and gas visible in this wide and deep image. One thing   
      that >remains unexplained is the unusually small globular star   
      clusters, seen as faint dots on the image. Most elliptical galaxies   
      have more and brighter globular clusters than NGC 1316. Yet the   
      observed globulars are too old to have been created by the recent   
      spiral collision. One hypothesis is that these globulars survive from   
      an even earlier galaxy that was subsumed into NGC 1316. Another   
      surprising attribute of NGC 1316, also known as Fornax A, is its giant   
      lobes of gas that glow brightly in radio waves.
