   Explanation: Only twenty-five years ago, [6]Comet Hale-Bopp rounded the
   Sun and offered a dazzling spectacle in planet Earth's night skies.
   [7]Digitized from the original astrophoto on 35mm color slide film,
   this classic image of the Great Comet of 1997 was recorded a few days
   after its perihelion passage on [8]April 1, 1997. Made with a camera
   and telephoto lens piggy-backed on a small telescope, the 10 minute
   long, hand-guided exposure features the memorable [9]tails of
   [10]Hale-Bopp, a whitish dust tail and blue ion tail. Here, the ion
   tail extends well over ten degrees across the northern sky. In all,
   [11]Hale-Bopp was reported as visible to the naked eye from late May
   1996 through September 1997. Also known as C/1995 O1, Hale-Bopp is
   recognized as one of the most compositionally [12]pristine comets to
   pass through the inner Solar System. A visitor from the distant
   [13]Oort cloud, the comet's next perihelion passage should be around
   the year 4380 AD. [14]Do you remember [15]Hale-Bopp?
